This link is similar to what you've found:
http://gcc.gnu.org/onlinedocs/gcc-3.3.3/gcc/Solaris-Pragmas.html#Solaris%20Pragmas

but this one is different and possibly later:
http://gcc.gnu.org/onlinedocs/gcc/Symbol_002dRenaming-Pragmas.html#Symbol_002dRenaming-Pragmas
which reads, "These pragmas are only available on platforms whose system 
headers need them."
and perhaps by implication the corresponding macros are there either.

This raises an interesting question.  By adding "__PRAGMA_REDEFINE_EXTNAME" to 
the
command line "sys/stat.h" did NOT "#define stat,fstat,lstat ..." since the 
issue is
CVS and Solaris are both attempting to #define the same tokens and don't 
compilers
quietly ignore #pragma statements they don't understand?

See the test program below which compiles and runs with no errors.  If we 
believe
the test program the redefine_extname pragma is just not implemented.  If so I'm
sorry as I sent us barking up the wrong tree.
