Nothing beyond what is normally required to use gnulib: i.e., invoke gl_EARLY, gl_INIT and so on (all is explained in the last output from gnulib-tool). > - Is it enough to > - add to configure.in > gl_STDLIB_H No, add gl_EARLY and gl_INIT instead. They are in gnulib-*.m4, which should be generated by gnulib-tool. They set up the gnulib modules properly, and will invoke gl_STDLIB_H if necessary. Generally, see the chapter 'Invoking gnulib-tool' in the gnulib manual. > - convert the implementation file construct from: > #ifdef STDC_HEADERS > # include <stdlib.h> > ... > #endif > to: > #include <stdlib.h> > #ifdef STDC_HEADERS > ... > #endif > (that is, move the #include <stdlib.h> to top-level, > without any surrounding preprocessor conditionals)? Yes. > - Is it wise to remove `AC_HEADER_STDC' from configure.in? In all of my projects, I assume standard C header files exists and never had any reports of problems. However, if your project is special and needs to build on systems that doesn't have proper compilers and libraries, you may want to use it. My understanding is that this is something of an autoconf antiquity. Of course, if you remove AC_HEADER_STDC you should remove the STDC_HEADERS checks as well. /Simon
