Yes, there are several ways to achieve that... but I meant that maybe some
projects will only compile with GCC (or run properly if compiled with GCC),
because they assume quirks in implementation, invalid syntax in language
standards but valid in GCC, and things like that.  Like the reasons why Linux
kernel does not compile with LLVM.  I think that many projects might have
similar problems if the compiler is not GCC.

E.g., even after years of efforts getting the archive compiled with Clang:

  "22202 packages have been rebuild. Among them, 1261 (5.7 %) failed."

  http://clang.debian.net/

I suspect that the numbers if using open64 compiler will be much worse.
