m4-1.4.12 make check throws many errors

On Solaris 10 Update 6 with latest kernel patches. Sun Studio 12 compiler
used here. I used GNU make and all other tools were vendor supplied.

I am attempting to make a 64-bit AMD64 executable here.

The binary is in fact created via configure -- make with nothing specified
other than --prefix

bash-3.2$ find . -type f -name m4
./src/m4
bash-3.2$ file ./src/m4
./src/m4: ELF 64-bit LSB executable AMD64 Version 1 [SSE2 SSE FXSR FPU],
dynamically linked, not stripped
bash-3.2$ ldd ./src/m4
        libthread.so.1 =>        /lib/64/libthread.so.1
        libc.so.1 =>     /lib/64/libc.so.1
        libm.so.2 =>     /lib/64/libm.so.2

Things go pretty badly after this.

All of your failures look like they involve regular expressions.  I'm
guessing that there is some bug present in 1.4.12 where the regex engine
was not prepared for a 64-bit machine.

There have been upstream fixes to regex.c in the meantime.  Would you mind
repeating your tests on a more recent snapshot, to see if we have fixed
things, or need to do further investigation?

Bug: m4-1.4.12 test phase

Hello, here is the build log of m4-1.4.12 in my Gentoo Linux system.
It uses gcc-4.3.2 and glibc-2.7. One of the tests have failed. Thanks
for your efforts in developing m4.

Fabio Correa.

Thanks for the report.

This has been previously reported.  It is a bug in the gentoo sandbox, and
not in m4.  That said, m4 can still work around it:

You may also be interested in trying a more recent snapshot, where the m4
patch is in place:
