Hi All,

According to the documentation page:

http://docs.scipy.org/doc/numpy/reference/distutils.html

Function add_library allows the following keywords:

      extra_f77_compiler_args

      extra_f90_compiler_args

however setting them seem to have no effect for my extension. Digging deeper, I discovered,

the documentation is inconsistent with the implementation, as per

https://github.com/numpy/numpy/blob/v1.11.0/numpy/distutils/fcompiler/__init__.py#L569

https://github.com/numpy/numpy/blob/v1.11.0/numpy/distutils/fcompiler/__init__.py#L583

And indeed, setting extra_f77_compile_arg has the effect I was looking for.

Fixing it is easy, but I am less certain whether we should fix the docs, or the code.

Given that add_extension lists extra_compile_args, extra_f77_compile_args, etc, I would think it

Is the documentation that need to change.

Please confirm, and I will open up a pull request for this.

Thank you,

Oleksandr
