As xterm modifies the 50 exported termcap, this would cause those modifications to be ignored. 51 kcah 52 53 hack wi-at-big-endian-bus 54 cdate 15 Mar 2002 55 who martin 56 file dev/ic/wireg.h 57 descr Add an option to access the underlying bus in big endian byte order 58 to work around deficiencies in bus_space_{read,write}_* macros. 59 Those don't allow the implementation of a proper pcmcia bus space 60 tag. 61 kcah 62 63 hack specific knowledge of colours in curses code 64 cdate Sun Apr 6 11:05:24 BST 2003 65 who jdc 66 file lib/libcurses/color.c : r1.24 67 descr 68 Swap red/blue and yellow/cyan colours for COLOR_OTHER. 69 Fix is to enhance libtermcap to understand terminfo-style % sequences. 70 See also: 71 http://mail-index.NetBSD.org/tech-userlevel/2003/04/06/0000.html 72 kcah 73 74 hack Compensation for differing types of LINUX_USRSTACK and USRSTACK 75 cdate 21 Aug 2003 76 who he 77 file sys/miscfs/procfs/procfs_linux.c : 1.14 78 descr 79 Not all ports have LINUX_USRSTACK and/or USRSTACK defined as 80 literals/constants, but refer to variables of a type which is 81 not "unsigned long", causing compilation of procfs_linux.c to 82 fail with "makes integer from pointer without a cast". This 83 is observed on e.g. the sun3 port. Ideally the "types" for 84 symbols should be consistent across all ports. 85 kcah 86 87 hack GCC2 isn't C99 88 cdate 5 December 2003 89 who mrg 90 file gnu/dist/binutils/ld/ldlex.c: r1.2 91 descr 92 ldlex.c is generated from ldlex.l and we get macro redefinition 93 errors from it if __STDC_VERSION__ is not C99 compliant. This 94 hack forces NetBSD 1.6 and later systems to also include <stdint.h> 95 to get the relevant definitions. This hack should be backed out 96 when all platforms have switched away from GCC2. 97 kcah 98 99 hack gcc-strict-aliasing 100 cdate 6 August 2004 101 who junyoung 102 pr 26516 103 file src/usr.sbin/racoon/racoon/Makefile : 1.21 104 descr 105 GCC issues a warning "dereferencing type-punned pointer will break 106 strict-aliasing rules" when compiling 107 crypto/dist/kame/racoon/crypto/openssl.c with -O[23s]. Note that this 108 is due to use of type casting in a non-standard way in the code and 109 not a compiler bug. Once a new release of KAME with a proper fix 110 applied is imported this should be backed out. 111 kcah 112 113 hack gcc4 wrong uninitialised variable 114 mdate 10 May 2006 115 who mrg 116 file bin/ksh/eval.c : 1.6 117 file bin/sh/histedit.c : 1.39 118 file bin/sh/parser.c : 1.60 119 file bin/systrace/systrace.c : 1.33 120 file crypto/dist/heimdal/kdc/524.c : 1.10 121 file crypto/dist/ssh/sftp.c : 1.20 122 file crypto/dist/ssh/ssh-keysign.c : 1.11 123 file dist/ipf/lib/hostname.c : 1.2 124 file dist/ipf/tools/ipmon.c : 1.8 125 file dist/ntp/ntpd/refclock_shm.c : 1.4 126 file dist/ntp/sntp/timing.c : 1.3 127 file dist/pppd/pppstats/pppstats.c : 1.3 128 file dist/smbfs/lib/smb/rap.c : 1.6 129 file dist/tcpdump/print-zephyr.c : 1.5 130 file gnu/libexec/uucp/uucico/uucico.c : 1.6 131 file lib/libc/citrus/citrus_csmapper.c : 1.6 132 file lib/libc/citrus/citrus_pivot_factory.c : 1.5 133 file lib/libc/inet/inet_cidr_ntop.c : 1.3 134 file lib/libc/inet/inet_ntop.c : 1.3 135 file lib/libc/stdio/vfwprintf.c : 1.8 136 file libexec/ld.elf_so/arch/sparc64/mdreloc.c : 1.39 137 file sbin/fsck_ext2fs/dir.c : 1.19 138 file sbin/routed/rtquery/rtquery.c : 1.18 139 file sys/crypto/cast128/cast128.c : 1.9 140 file sys/ddb/db_command.c : 1.86 141 file sys/dev/fss.c : 1.25 142 file sys/dev/ic/midway.c : 1.71 143 file sys/dev/pci/machfb.c : 1.45 144 file sys/dist/ipf/netinet/ip_nat.c : 1.10 145 file sys/dist/ipf/netinet/ip_rpcb_pxy.c : 1.8 146 file sys/dist/pf/net/pf.c : 1.22 147 file sys/fs/udf/udf_vnops.c : 1.4 148 file sys/kern/kern_sig.c : 1.219 149 file sys/kern/tty.c : 1.181 150 file sys/net/bpf.c : 1.116 151 file sys/net/zlib.c : 1.26 152 file sys/netinet/in.c : 1.107 153 file sys/netsmb/smb_smb.c : 1.27 154 file sys/netsmb/smb_trantcp.c : 1.22 155 file sys/nfs/nfs_serv.c : 1.108 156 file sys/nfs/nfs_socket.c : 1.129 157 file sys/nfs/nfs_syscalls.c : 1.91 158 file sys/ufs/lfs/lfs_vfsops.c : 1.207 [also (char *)] 159 file usr.bin/ftp/ftp.c : 1.140 160 file usr.bin/find/function.c : 1.54 161 file usr.bin/mail/tty.c : 1.20 162 file usr.bin/nl/nl.c : 1.7 163 file usr.bin/systat/keyboard.c : 1.23 164 file usr.bin/usbhidctl/usbhid.c : 1.29 165 file usr.bin/vi/cl/cl_read.c : 1.5 166 file usr.bin/vi/ex/ex_cscope.c : 1.12 167 file usr.bin/vi/ex/ex_tag.c : 1.19 168 file usr.bin/vi/vi/v_txt.c : 1.15 169 file usr.sbin/altq/altqstat/qdisc_rio.c : 1.4 170 file usr.sbin/cron/do_command.c : 1.19 171 file usr.sbin/timed/timed/slave.c : 1.15 172 descr 173 GCC 4.1 gets many uninitialised variable warnings wrong.

There is some 348 disagreement whether they should have associated relocation 349 entries. Both the SPARC 32-bit and 64-bit ELF specifications 350 say that they should have relocation entries, but the 32-bit 351 SPARC binutils do not generate them, and now the 64-bit SPARC 352 binutils have stopped generating them too. 353 354 To provide binary compatibility, we will check the first entry, 355 if it is reserved it should not be of the type JMP_SLOT. If it 356 is JMP_SLOT, then the 4 reserved entries were not generated and 357 our index is 4 entries too far, so we frob the rela pointer. 358 kcah 359 360 361 port arm 362 363 hack gcc-unsigned-compare 364 cdate 09 Mar 2002 365 mdate 18 Mar 2002 366 who bjh21 367 file dist/bind/lib/nameser/ns_parse.c : 1.3 368 file dist/dhcp/minires/ns_parse.c : 1.3 369 file dist/dhcp/omapip/result.c : 1.2 370 file dist/dhcp/server/failover.c : 1.3 371 file gnu/dist/gawk/eval.c : 1.4 372 file gnu/dist/toolchain/bfd/bfd.c : 1.2 373 file gnu/dist/toolchain/bfd/format.c : 1.2 374 file gnu/dist/toolchain/gdb/target.c : 1.2 375 file sys/kern/vfs_subr.c : 1.172 376 descr When checking that a potentially-unsigned enum is >= 0, assign 377 it to an int first.
