* Move .h file names out of the *.m4 files.Bruno Haible2021-12-151-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is useful because Autoconf macros defined in *.m4 files can be AC_REQUIREd.

* include_next: do not check for standard headers like stddef.hPaul Eggert2011-01-181-2/+2
| | | | | | | | | | | | | | | | I found this problem when modifying Emacs to use gnulib. I noticed that it added HAVE_STDDEF_H to config.h, even though gnulib always assumes <stddef.h> exists as per README and this symbol is unnecessary. * m4/include_next.m4 (gl_NEXT_HEADERS): New macro, which does not use AC_CHECK_HEADERS_ONCE, but which otherwise contains what gl_CHECK_NEXT_HEADERS used to contain. This makes 'configure' run faster for headers like stddef.h that are known to exist. (gl_CHECK_NEXT_HEADERS): Use it. * m4/float_h.m4 (gl_FLOAT_H): For float.h, use gl_NEXT_HEADERS rather than gl_CHECK_NEXT_HEADERS. * m4/stdarg.m4 (gl_STDARG_H): Likewise, for stdarg.h. * m4/stddef_h.m4 (gl_STDDEF_H): Likewise, for stddef.h.
