The rationale is that all supported compilers should behave in the same way, that is, lower cases and append underscore to fortran symbols. Different compilers may behave differently in this respect and with additional switches one can "tune" a compiler as needed. Earlier compaq_visual_fortran_compiler did not follow this convention and hence the changes. Sorry that it broke some of your codes and I hope it is not too much trouble for you to fix them.
But do you do with Third party delivered libraries you want to wrap. We have a set of huge libraries where we can't compile of our own. From time to time we need/have fortran wrapper around these libraries that then need to be wrapped for python. These Fortran wrapper are only needed for the Python wrapper and as such are compiled as library unsing distutils. Would it be possible to provide a mechanism to allow user defined settings for the "switches" to make the libraries work?
Could you give a more detailed example of the fortran wrapper and how do you wrap it to Python? If these wrappers can be modified e.g. by inserting f2py directives, then `fortranname` .pyf file command might be what you need.
Now i have a binary Fortran library named 'provided'. 'provided' provides a function 'subroutine foo()' which leads to a symol '_FOO@0' in the library. Now i want to write a function that makes intensive use of 'foo', so I write a Fortran routine 'subroutine usefoo()' that is specific to python ant I wrap it unsing f2py. Because 'usefoo' is only usefull for my Python extension library I include it's sourcecode in my Python Project and build it as 'fortran_libraries' using scipy distutils. With the switches' settings as they are now this does not work, because the linker looks for '_foo_' instead of '_FOO' or '_FOO@0'.
