将Fortran转换为C或c++

I have some numeric code that I need to convert to C or C++. I tried using f2c, but it won't work on the Fortran code. f2c complains because the code uses C style preprocessor directives (#include). The code's readme states that it is Fortran77, that works with the fort77 linker, that would expand those includes.I have some numeric code that I need to convert
