Hi All,
I could really use some help here from someone who has a better
understanding of how the config/Makefile system works than I do.
In my libvtv/configure.ac file, I have:
AC_GNU_SOURCE
AC_CHECK_FUNCS([__secure_getenv])
AC_GNU_SOURCE
AC_CHECK_FUNCS([secure_getenv])
There's nothing in Makefile.am that makes use of the substitution
variables, so configure doesn't actually emit code to define the
matching preprocessor macros.
I tried to change that, by putting "DEFS = @DEFS@" into
libvtv/Makefile.am (libvtv/Makefile.in is derived from that). The diff
below is slightly garbled, but you get the idea.
diff --git a/libvtv/Makefile.am b/libvtv/Makefile.am

But I ended up with:

(The caret is at the wrong position, IMHO.)
But I suspect something went wrong with regenerating Makefile.in. Have
you got automake 1.11? Then you could make the change, regenerate
Makefile.in, and try again.
