Let me nitpick a bit:
ifdef([m4_pattern_allow],
[m4_pattern_allow([^AM_CFLAGS$])])dnl
(note the anchors too). I insist on the dnl: currently automake dump
a long series of empty lines coming from there. And BTW, instead of
# Autoconf 2.50 wants to disallow AM_ names. We explicitly allow
# the ones we care about.
ifdef([m4_pattern_allow], [m4_pattern_allow([AM_CFLAGS])])
ifdef([m4_pattern_allow], [m4_pattern_allow([AM_CPPFLAGS])])
ifdef([m4_pattern_allow], [m4_pattern_allow([AM_CXXFLAGS])])
ifdef([m4_pattern_allow], [m4_pattern_allow([AM_OBJCFLAGS])])
ifdef([m4_pattern_allow], [m4_pattern_allow([AM_FFLAGS])])
ifdef([m4_pattern_allow], [m4_pattern_allow([AM_RFLAGS])])
ifdef([m4_pattern_allow], [m4_pattern_allow([AM_GCJFLAGS])])
you can
# Autoconf 2.50 wants to disallow AM_ names. We explicitly allow
# the ones we care about.
ifdef([m4_pattern_allow],
[m4_pattern_allow([^AM_(C|CPP|CXX|OBJC|F|R|GCJ)FLAGS$])])dnl
