Nice idea.

# Autoconf machinery:
m4/guile.m4

# Snarfing support for 1.4
scripts/guile-1.4/guile-doc-snarf
scripts/guile-1.4/guile-func-name-check
scripts/guile-1.4/guile-snarf.awk

# Snarfing support for 1.6
scripts/guile-1.6/guile-doc-snarf
scripts/guile-1.6/guile-doc-snarf.awk

# This header is mailutils specific. It does, however, contain 1.4
# vs. 1.6 compatibility defines and declarations (see lines 24 -- 44)
include/mailutils/guile.h

Note, however, that the header is oriented only on the functions MU
uses. Creating a universal compatibility layer will require, in
practice, writing a compatibility library, that would provide interfaces
for functions that differ in both versions of Guile.
