Close.  We'll add 

  #include <bits/features.h>
  ...
  #if defined(__USE_SVID)
    using _C_legacy::matherr;
  #endif

just like you see in Glibc headers.  Anybody who really wants 
Sun cruft can send in a patch to add

  #if defined __USE_SUN_CRUFT
    using _C_legacy::suncruft;
  #endif

too.  Yes, it's ugly, but it's good ugly, like the uglified names.
