Well, perhaps I understand less of autoconf than I thought I did. I
tried to put GIT_VERSION=`$(ac_top_srcdir)/GIT-VERSION-GEN` in there
before even looking for help here, but $(ac_top_srcdir) isn't set at
that point. I literally have
GIT_VERSION=`./GIT-VERSION-GEN`
AC_SUBST(GIT_VERSION)
AH_TEMPLATE([GIT_VERSION],
[Git revision of this build])
in my configure.ac file. It seems like AC_CONFIG_COMMAND runs too
late for the variables to be put in config.h, is that right?
I suspect I'm revealing a deep ignorance of what is actually going on
under the hood here, but I really appreciate the help.
