* Revision 5.2 1993/08/03 19:28:39 syd
* Elm tries to replace the system toupper() and tolower() on current
* BSD systems, which is unnecessary. Even worse, the replacements
* collide during linking with routines in isctype.o. This patch adds
* a Configure test to determine whether replacements are really needed
* (BROKE_CTYPE definition). The <ctype.h> header file is now included
* globally through hdrs/defs.h and the BROKE_CTYPE patchup is handled
* there. Inclusion of <ctype.h> was removed from *all* the individual
* files, and the toupper() and tolower() routines in lib/opt_utils.c
* were dropped.
* From: chip@chinacat.unicom.com (Chip Rosenthal)
