Namely, gcc +dnl does not warn about some things, and on some systems (Solaris and Interix) +dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side +dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead +dnl of plain '__STDC__'. +dnl +dnl PRAGMA_COLUMNS can be used in files that override system header files, so +dnl as to avoid compilation errors on HP NonStop systems when the gnulib file +dnl is included by a system header file that does a "#pragma COLUMNS 80" (which +dnl has the effect of truncating the lines of that file and all files that it +dnl includes to 80 columns) and the gnulib file has lines longer than 80 +dnl columns. + +AC_DEFUN([gl_INCLUDE_NEXT], +[ + AC_LANG_PREPROC_REQUIRE() + AC_CACHE_CHECK([whether the preprocessor supports include_next], + [gl_cv_have_include_next], + [rm -rf conftestd1a conftestd1b conftestd2 + mkdir conftestd1a conftestd1b conftestd2 + dnl IBM C 9.0, 10.1 (original versions, prior to the 2009-01 updates) on + dnl AIX 6.1 support include_next when used as first preprocessor directive + dnl in a file, but not when preceded by another include directive.
