* ldmain.c: quit using exit
* *.sc: use *(COMMON) rather than [COMMON]
* ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
to allow preprocessing of .l file.
* Makefile.in: New ldlex.l mangling
* ldexp.c (fold_binary): perform expressions with % and / in
integer.
* ldfile.c (open_a): open archives on VMS in a special way
* lderror.c: forgot to check in from a long while ago
* ldtemplate: Remove ldfile_add_library_path calls;
just use the SEARCH_DIR commands in the script files.
* Makefile.in: Add LIB_PATH macro, which if set is used to replace
the SEARCH_DIR commands in the scripts (using ugly sed magic).
This is primarily intended for cross-linking, where you would
place libaries in a different place than native libraries.
Also, emulations made from ldtemplate now use $(srcdir).
* ldglda29k.sc: Change SEARCH_DIR commands to a conventional
form; people can use the Makefile's LIB_PATH to override.
