Thanks for the report.  However, SunOS-5.7 (aka Solaris 7) is so old
that gnulib no longer actively caters to it:

https://www.gnu.org/software/gnulib/manual/gnulib.html#Target-Platforms

The problem appears to be that the gnulib replacement headers are
missing a workaround to pick up the proper system header that defines
'struct stat'; it may be fixable in gnulib.  If you want to tackle
patching gnulib to cater to this old of a system, and your patches are
maintainable, then there is a possibility that a future m4 release using
newer gnulib will work on a system that old.  But for now, I'm afraid
that you are trying to port to museumware and won't get very far.
