Re: AC_PROG_CC NextStep failure

[Paul Eggert]

Thanks for the bug report and patch.  I installed the following
somewhat more-conservative patch instead.

2003-11-17  Paul Eggert  <address@hidden>

        * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
        into the initial confdefs.h, to work around a bug in NextStep 3.3
        patch 3 reported by Eric Sunshine.
