[cfe-dev] [PATCH] PR5326, Clang needs support for _Complex_I and _Imaginary_I as intrinsics.

[Edward O'Callaghan]

Thanks for the pointer Eli !

Please see attached update, I can't seem to get it work work as expected.

-bash-3.2$ ../../llvm/Debug/bin/clang-cc -fsun-extensions divdc3_test.c
clang-cc: Unknown command line argument '-fsun-extensions'.  Try:
'../../llvm/Debug/bin/clang-cc --help'

I must be missing something somewhere, can you please review my patch carefully?

Thanks for your time,
Edward.
