Bison output file name test failure on Solaris 10 (Sun C++ 5.12)

[Paul Eggert]

After my recent spate of commits, Bison HEAD passes all its tests on 
Solaris 10 when compiled with Oracle Solaris Studio 12.3 (also known as 
Sun C 5.12), except for this test:

113: Output file name: `~!@#$%^&*()-=_+{}[]|\:;<>, .' FAILED (output.at:293)

tests/testsuite.dir/113/testsuite.log is attached, and indicates that 
it's an internal error in the C++ compiler (though not the C compiler). 
I don't see this error in Oracle Developer Studio 12.6 (the current 
release), so I doubt whether this issue is work fixing per se. That 
being said, a C or C++ compiler is within its rights to reject file 
names that are not portable POSIX file names, so perhaps the test should 
be altered to detect compilers that are pickier about file names.
