* Makefile.in (CFILES): Add safe-ctype.c.
(REQUIRED_OFILES): Add safe-ctype.o.
* argv.c: Define ISBLANK and use it, not isspace.
* basename.c, cplus-dem.c, fnmatch.c, pexecute.c, strtod.c,
strtol.c, strtoul.c: Include safe-ctype.h, not ctype.h. Use
uppercase ctype macros. Don't test ISUPPER(c)/ISLOWER(c)
before calling TOLOWER(c)/TOUPPER(c).
* configure.in: if with-newlib, point to it for includes
rather than using the installed includes, for target builds.
If cygwin, override function list only for target builds.
* configure: regenerate
Note from DJ: I waited a week for gcc approval and got none, but
we need this patch for cygwin builds *now*. I'll fix it later if
need be.
