 1.28  15-Mar-2012  christos - ansify, knf.
- no functional changes
 1.27  25-Oct-2009  christos branches: 1.27.6;
revert some of dsl's changes to make things build on i386; he can undo what
he wants when he comes back.
 1.26  25-Oct-2009  dsl Lint is differentially far too picky...
Remove some warnings that only appear on i386 (not on amd64) and that
for some reason best known to others are deemed fatal for i386.
Making this code 'pass lint' does absolutely nothing for its readability (etc).
 1.25  24-Oct-2009  dsl Remove a load of pointless casts - one that even lint doesn't bleat about.
 1.24  24-Oct-2009  dsl Check for EOF before erroring fgets() with length <= 0.
If length is invalid, set errno = EINVAL and __SERR as well returning NULL.
Should let me close PR/41992.
 1.23  14-Oct-2009  dsl Change a while () {} into a do {} while() so that fgets(buf, 1, file)
detects EOF on an empty file.
Fixes most of PR/41992
 1.22  05-Feb-2009  lukem sign-compare fix
 1.21  03-Jun-2007  christos Make these work with _FORTIFY_SOURCE, by overriding the fortified definitions
 1.20  14-Dec-2003  lukem remove superfluous assignment
 1.19  10-Oct-2003  simonb Remove another unneeded cast to size_t.

Pointed out by Anil Madhavapeddy in private email.
 1.18  09-Oct-2003  simonb No need to cast "len" to a size_t now that "len" is a size_t.
 1.17  08-Oct-2003  itojun avoid signed->unsigned assignment. openbsd PR 1709
 1.16  07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.
 1.15  18-Jan-2003  thorpej Merge the nathanw_sa branch.
 1.14  07-Dec-2001  yamt - make FILE structure extensible without breaking binary-compatibility.
- add fputwc, fgetwc, fwide and related functions.
- add hooks needed to maintain the orientation of file stream.
 1.13  14-Nov-1999  explorer branches: 1.13.6;
missing ;
 1.12  20-Sep-1999  lukem branches: 1.12.4;
back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.
 1.11  16-Sep-1999  lukem * use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif
 1.10  15-Nov-1998  christos change len from size_t to int so that len = fp->_r does not get promoted
to unsigned. cast len appropriately to size_t later.
 1.9  07-Sep-1998  kleink Sloppy stdio stream lock tracking.
 1.8  03-Feb-1998  perry remove obsolete register declarations
 1.7  19-Jan-1998  jtc Use FLOCKFILE() and FUNLOCKFILE() macros from reentrant.h so that stdio
can be made thread-safe.
 1.6  13-Jul-1997  christos Fix RCSID's
Fix gcc warnings.
Add prototypes for functions that were declared in more than one place
to local.h or extern.h and use that instead.
 1.5  25-Mar-1995  jtc change second arg of fgets() from size_t to int
 1.4  02-Feb-1995  jtc branches: 1.4.2;
Merged with 4.4lite.
Changed to conform to NetBSD's new RCS Id convention.
 1.3  26-Aug-1993  jtc Declare rcsid strings so they are stored in text segment.
 1.2  01-Aug-1993  mycroft Add RCS identifiers.
