Produces seemingly mis-located warnings, both on recent trunk:
/gnu $ g++ -S vis.cpp -o vis.asm
vis.cpp: In function 'int foo(int)':
vis.cpp:11: warning: visibility attribute not supported in this configuration;
ignored
vis.cpp: At global scope:

Still present, although the location has slipped slightly for the warnings on
the function declarations with no body.
$ g++ -S vis.cpp -o vis.asm
vis.cpp: In function 'int foo(int)':
vis.cpp:11: warning: visibility attribute not supported in this configuration;
i
gnored
vis.cpp: At global scope:
vis.cpp:30: warning: visibility attribute not supported in this configuration;
i
gnored
vis.cpp:30: warning: visibility attribute not supported in this configuration;
i
gnored
Confirming, but lowering the severity and priority.

Just reconfirmed with recent pre-4.5.0 HEAD:
$ /gnu/gcc/install-pr42811-3/opt/gcc-tools/bin/g++-4.exe -S vis.cpp -o vis.asm
vis.cpp:30:47: warning: visibility attribute not supported in this
configuration; ignored
vis.cpp: In function 'int foo(int)':
vis.cpp:11:1: warning: visibility attribute not supported in this
configuration; ignored
vis.cpp: At global scope:
vis.cpp:30:47: warning: visibility attribute not supported in this
configuration; ignored
Still trivial.
