getcwd: support coreutils better Like strtod, getcwd incorrectly referred to HAVE_RAW_DECL_GETCWD, but this might not be correct in coreutils, which disables the raw decl checks. Problem reported by Nagendra in <http://bugs.gnu.org/10305#192>. * lib/getcwd.c (__getcwd): Do not depend on HAVE_RAW_DECL_GETCWD. * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Test the getcwd function, not any macro, since getcwd.c wants the function. * m4/getcwd.m4 (gl_FUNC_GETCWD): Don't define HAVE_MINIMALLY_WORKING_GETCWD if the code doesn't compile, as might happen if there's a macro but no function.
