[adding bug-autoconf, because of the shell bug shown here]

Wow.  Your shell is buggy.  $? is never supposed to hold a non-numeric
value.  Your config.log shows that you loaded a config.site, where you
pre-define SHELL=sh and ac_cv_path__PATH_SH='/moztools/ash.exe, so maybe
it just means you have a broken ash installed?  Does OS/2 even come with a
default pre-built bourne-style shell, or is ash something you built
yourself?  Can you upgrade to a better shell?

At any rate, your platform seems more and more like a lost cause.  The
fact that configure doesn't even complete means that autoconf-generated
scripts are not portable to your platform; we would have to fix that
first, but we can't even write an autoconf patch to work around corruption
in $? unless you can find a workaround.  Meanwhile, since you obviously
can't rename an in-use file, you can get past this check by calling
'./configure M4_cv_func_rename_open_file_works=no'.
