That's odd. Where was the gettext macro originally defined?

This warns about the use of a C99-ism in code that is protected by "#if 
199901L <= __STDC_VERSION__", so it must be a false alarm, and you're 
right tno not worry about it.

Ouch. This appears to be a compiler bug, as a compiler should never 
generate invalid assembly-language code. I cannot reproduce the problem 
on Solaris 10 sparc (32-bit) with Oracle Developer Studio 12.5. You are 
on Solaris 10 x86 (32-bit) and are using 12.3. Do you observe the same 
compiler bug with 12.5 or 12.6 beta? If so, I suggest reporting it as a 
bug to Oracle.

What happens if you compile with -xO2?

Although I cannot reproduce the problem in my environment, I think I see 
why it's happening. I installed the attached patches into Gnulib; do 
they fix your problem?
