xlc-wrap is my own script. It is quite simple:
#!/bin/sh
exec xlc -qnosearch "$@" -qsearch=/usr/include
It is used to work around a non-standard behavior of the compiler, where
/usr/include/ is effectively first in the header search path (before any
-I directories). Obviously an issue for Gnulib's replacement headers.
I haven't gotten around yet to submitting this issue formally to Gnulib.
For an example of how such a workaround can be integrated, look at
AC_ZOS_USS in m4/arch.m4 in the GNU Gawk source. It's fairly
comprehensive in addressing the toolchain weirdness of z/OS.

Line 648 is marked below:
-----begin locale.h excerpt-----
#if 1
# if 1
# if !(defined __cplusplus && defined GNULIB_NAMESPACE)
# undef duplocale
# define duplocale rpl_duplocale
# endif
_GL_FUNCDECL_RPL (duplocale, locale_t, (locale_t locale) _GL_ARG_NONNULL
((1))); <---HERE
_GL_CXXALIAS_RPL (duplocale, locale_t, (locale_t locale));
# else
# if 1
_GL_CXXALIAS_SYS (duplocale, locale_t, (locale_t locale));
# endif
# endif
# if 1
_GL_CXXALIASWARN (duplocale);
-----end locale.h excerpt-----
When I looked at the preprocessed source, the first mention of locale_t
came from that line. So it seems that while all other systems provide
locale_t, z/OS is an exception.

Sure...
-----begin stdlib.h excerpt-----

typedef struct div_t

-----end stdlib.h excerpt-----
These errors are probably cascaded from the earlier syntax error, so I
wouldn't worry about them for now.
