include:
* safe-ctype.h (HC_UNKNOWN, HC_ASCII, HC_EBCDIC, HOST_CHARSET):
New #defines.
libiberty:
* safe-ctype.c: Separate out EOF==-1 check. Use HOST_CHARSET
for charset determination.
gcc:
* aclocal.m4 (gcc_AC_C_CHARSET): Delete.
* configure.in: Don't use gcc_AC_C_CHARSET.
* configure, config.in: Regenerate.
* config/i370/i370.c, config/i370/i370.h: Use
(HOST_CHARSET == HC_EBCDIC) or (HOST_CHARSET == HC_ASCII)
instead of HOST_EBCDIC or !HOST_EBCDIC. Clarify comments a tad.
