What do you think of the following patch? This looks useful to me for
nailing down an independent issue in lib/inttypes_.h: with this, it
actually works to override the test temporarily with
./configure gl_cv_header_working_inttypes_h=yes
(and thus decouple this from other build failures).
Cheers,
Ralf

* m4/inttypes.m4 (gl_INTTYPES_H): Use AC_CACHE_CHECK so that the
test for conforming inttypes.h is both announced and cached.
