We cannot do anything with such a vague problem description. Nor can we
apply a patch that appears to make the autoconf macros more unreliable
without actually fixing anything.

So, please, can you tell a "How to reproduce" recipe of the two problems?
It it involves source code that it not public, then can you shrink it to
a reproducible sample that is small enough that you can post it? And, of
course, with every bug report, you MUST mention the platform, compiler, and
compiler options that you use.

The symptoms that you mention make me think of a configure file that was
incorrectly generated, or of a gl_cv_have_include_next variable that was
set to an invalid value in the environment or in a config.site file, or of
m4 quoting bugs in your configure.ac and *.m4 files. But that is just a
wild guess of mine, given that your bug report had no useful info.
