We have support for all important toolchains (gcc, clang, MSVC).  (when testing the PR on libfontmanager and freetype I had this enabled on all our SAP supported platforms).
However it might not work for all versions of these compilers.
And when building HS with lto support I remember a few jtreg tests failed (so it  might need some more work to look into all details).
