The first step is (at least on /this/ GNU/Linux) already done, so the 
templated versions of the C99 functions do exist after including <cmath>.  
Plus, gcc/g++ on GNU/Linux readily (too readily?!) puts this stuff in the 
"std::" namespace plus exports it to the global namespace (as shown in my C++ 
example code; maybe one would have to use a commandline option to force some 
specific behaviour).

So, I don't think your approach would (in the short run) break anything for 
Linux.  However, at least the _GLIBCPP_USE_C99 macro setting should be dealt 
with by the auto-configure setup and be put into some central configuration.

At least, there seems to be some light at the end of the tunnel. :-)
