t-slibgcc-cygming revision 1.1 
      1 # Build a shared libgcc library for PECOFF with a DEF file
      2 # with the GNU linker.
      3 #
      4 # mkmap-flat.awk is used with the pe_dll option to produce a DEF instead
      5 # of an ELF map file.
      6 #
      7 # Warning: If SHLIB_SOVERSION or SHLIB_SONAME are updated, LIBGCC_SONAME
      8 # in mingw32.h and SHLIB_MKMAP_OPTS below must be updated also.
