New description:
Apple stopped supporting GCC in favour of clang. This is a metaticket to
track the status of building Sage with clang.
----
Packages failing to build (or causing other packages to fail to build)
with Clang:
* ATLAS -- probably impossible without Clint's help. Also mixes Fortran
and C code.
* eclib -- default parameters in `friend` declarations (?)
* Givaro -- causes build failure for !LinBox: assignment to `const`
variable
* Gfan (0.5) -- #12440
* Lcalc -- #12436, #12437
* libGAP -- some preprocessor / macro weirdness?
* !LinBox -- C++ problem
* pynac -- C++ template problem
* Python -- #16376 (fails to build `_sqlite3`, uses `-R<path>` instead of
`-Wl,-R,<path>`)
* R -- problematic due to mixture of C and Fortran code
* ratpoints -- #12473 (uses nested functions and GCC builtins not
supported by clang)
* Singular -- #12442
* Symmetrica -- #12439
----
Spkgs ignoring CC/CXX environment variables:
* FLINTQS -- #12428
* Sage -- #12443
