Thu Oct 8 08:52:48 1992 Steve Chamberlain (sac@thepub.cygnus.com) Now a bfd knows whether underscores are normally prepended to symbols in its file format. Helps with error messages. * aout-adobe.c, aout-target.h, bout.c, coff-a29k.c, coff-h8300.c, coff-z8k.c: targets set so they have leading underscore * coff-i386.c, coff-i960.c, coff-m68k.c, coff-mips.c, coff-m88k.c, coff-rs6000.c, coff-we32k.c, elf.c, ieee.c, srec.c: targets set without leading underscore flag * targets.c: add symbol leading char to xvec description * bfd-in.h (bfd_get_symbol_leading_char): new macro.
