The automake testsuite recently introduced a portability problem when it used AC_CONFIG_AUX_DIR([aux]) in a couple of tests. Unfortunately, Windows reserves aux as a special filename, so you cannot use a subdirectory named aux for this purpose; these tests needlessly fail under cygwin and other Windows ports. The name of the AC_CONFIG_AUX_DIR macro is somewhat unfortunate for portability, because a naive user is likely to choose "aux" as was done in the automake testsuite. You should consider either renaming the macro, or updating the macro to error out (or at least warn) if user tries to name their auxiliary directory "aux" on the grounds that their project will not port to cygwin, mingw32, or djgpp without changes. Also, the "File System Conventions" section of the manual should be updated to list all known filenames that will not port to Windows. This includes, but is not limited to, aux, com1, com2, lpt1, nul (the equivalent of Unix's /dev/null, but not tied to an absolute path), these special filenames with a suffix (such as aux.sh), and so forth. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://mail.gnu.org/mailman/listinfo/autoconf
