Hi Ludovic,

I'd prefer to use guile.m4, even though it uses guile-config. It insists.
Unfortunately, it does not work. For me.
configure.ac:140: the top level

If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.

As the comment says:
dnl AC_LIB_LINKFLAGS_FROM_LIBS is defined in gnulib/m4/lib-link.m4 and needs
dnl the file gnulib/build-aux/config.rpath.
This means that these two files have to be imported in your project for
this to work.
I hadn’t noticed that, and I reckon that this is unfortunate.
The change dates back to Feb. 2011, by Bruno, so we’d have to check the
rationale.
Thank you for the explanation.
I am a big fan of comprehensible error messages and, as you'd guess,
I don't think that "possibly undefined macro: AC_LIB_LINKFLAGS_FROM_LIBS"
qualifies. Adding an AC_REQUIRE() would likely trigger something more
meaningful. Having to trace down a comment in an m4 file is not
very friendly.
However, now that I know the issue, obviously I'll add these files to
the list of things I grab from gnulib. Thank you again.
Regards, Bruce
