Special Update/Build Instructions
---------------------------------

-  TODO:
-  Perhaps also modify CXXFLAGS (and/or CPPFLAGS).
-  We currently don't use anything of GMP's/MPIR's CC setting, and
   matching with the current compiler (``$CC``) is perhaps suboptimal.
-  Remove some files / directories not needed for Sage from upstream:
-  build.vc\* directories (Microsoft Visual C build files)
-  3.0.0-644faf502c56f97d9accd301965fc57d6ec70868
   was created by running the spkg-src script.
