Another problem I just noticed; there is a test for <ctype.h> functionality
in the check for ANSI C headers that fails on OS/390 because HAVE_EBCDIC is
defined, but the compiler is set to use ASCII literals. So configure decides
that the ANSI C headers are not available, even though they are.

On a slightly related topic, build/shtool uses hardcoded ASCII code values
for its "terminal bold sequence" which is not portable. E.g., it uses
	awk 'BEGIN { printf("%c%c%c%c", 27, 91, 49, 109); }'
so these codes are used literally on an EBCDIC host, which is garbage. If it
used the actual literals "^[[1m" instead, the same string would work on both
ASCII and EBCDIC hosts. This is hardly a tragedy, but I figured it should be
mentioned.
