Hopefully someone more familiar with mesa can do this. The difference between 'd' and 'D' in the symbol definition is local versus global. Maybe this is a hint to the problem. Use flags and emerge --info follow.

I'd say no-one really tests motif support anymore. You might want to file a bug upstream [1] and see what they have to say. If you do file a bug, please add "remi@gentoo.org" as a CC on the bug so I can track the issue. Thanks [1] https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa
Upstream bug filed.
It has to be in the build system, as the code didn't change from 7.7 to 7.8.

I think I found the problem: At some point mesa started to use the --visibilizy=hidden attribute if gcc supports it. Since in mesa libGLw is build by default as a static library this is of no consequence when linking. But in Gentoo the library is build as a shared library, and hence the visibility is important. By adding GLAPI to the function declaration in question, the problem should go away.
Created attachment 275607 [details, diff] Add GLAPI to the two functions in question This patch fixed it for me (amd64, gcc 4.5.2).
Could you also attach the patch at the upstream bug?
Created attachment 277319 [details, diff] possibly more complete patch that needs testing You need motif or lesstif to check this? I don't use those it applied fine for me but did not get called. the option would be '--enable-glw' was not on my system.
The patch works here.
Fixed in mesa-7.11_rc1
