Browse Source 
Needed when using ...libtcc1-usegcc=yes in lib/Makefile.

lib/bcheck.c: Add __clang__ for pragma diagnostic
lib/bt-log.c: Add pragma diagnostic as in lib/bcheck.c
lib/builtin.c: Add a lot of alias code to allow building with gcc/clang
lib/stdatomic.c: Same as lib/builtin.c
lib/tcov.c: Avoid clang compiler warning
