Thanks. Three more improvements on the patch:
- mbsrtowcs.m4 has the same problem.
- Before each AC_TRY_RUN invocation, there is already some code that
initializes the resulting cache variable for the cross-compiling case.
All that needs to be added is a no-op statement.
- One of the cross-compilation guesses was wrong.
I'm applying this:
2009-04-22 Yoann Vandoorselaere <yoan...@prelude-ids.com>
Bruno Haible <br...@clisp.org>
Fix cross-compilation results.
* m4/btowc.m4 (gl_FUNC_BTOWC): Use no-op statement, rather than empty
statement, as third argument of AC_TRY_RUN.
* m4/mbrtowc.m4 (gl_MBRTOWC_INCOMPLETE_STATE, gl_MBRTOWC_SANITYCHECK,
gl_MBRTOWC_NULL_ARG, gl_MBRTOWC_RETVAL, gl_MBRTOWC_NUL_RETVAL):
Likewise.
* m4/mbsrtowcs.m4 (gl_MBSRTOWCS_WORKS): Likewise.
* m4/wcsrtombs.m4 (gl_WCSRTOMBS_TERMINATION, gl_WCSRTOMBS_NULL):
Likewise.
* m4/wctob.m4 (gl_FUNC_WCTOB): Likewise.
* m4/wcrtomb.m4 (gl_FUNC_WCRTOMB): Likewise. Update for AIX 4.3.
* doc/posix-functions/wcrtomb.texi: Mention the bug on AIX 4.3.
