/opt/csw/include/libintl.h, line 132: #define gettext libintl_gettext

(I got this using the  -xdumpmacros=defs,loc option.)

I only have access to 12.4 on the system I am using, but that appears to
compile the test file I posted without error. Solaris Studio 12.2 gives

The errors from the assembler do not occur and the compilation finishes 
successfully.

Yes, the error goes away with the change you made. It's good that you 
managed to fix this.
