Should use C99 mode in gcc

Should add -std=c99 in setup.py

same error, change -std=c++11 to -std=c99 or add std=c99 in extra_compile_args causes another error:

using gcc-4.9.2 and gcc-4.8.5 both fail, do not know how to fix it? can @SeanNaren or someone fix this ? thanks in advance!!!

[freesouls]

the above problem was caused by myself, the source code is extra_link_args=['-Wl,-rpath,' + os.path.realpath(warp_ctc_path)] at some point I change it to extra_link_args=['-Wl,-rpath' + os.path.realpath(warp_ctc_path)] by accident, so the compilation failed.
