AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
* lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
&s;" test into the main program, as C99 might plausibly be
interpreted as not requiring support for this construction in
static initializers. Remove the "#if defined __xlc__" stuff, as
the bug is not present in recent xlc implementations, and they
reject the test for other (valid) reasons. People using ancient
xlc versions, if any, are suggested to update to fixed versions.
