Is it possible that those programs were not using a config.h? >> That part of the code has been unchanged >> since AC_SYS_LARGEFILE was added to specific.m4. > > Interesting, when was that?

According to NEWS, it was not in 2.13 (which was released 1999-05-01), but it was in the very next release, 2.50 (2001-05-21). The ChangeLog entry for the addition says "Import AC_SYS_LARGEFILE from largefile.m4 serial 12", so that sounds like there was an add-on .m4 file with the same functionality floating around prior to that - I don't know where to find copies of that file. zw _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
