 I have this example fortran file from the slicot library, where the $ sign
 is used to make line extension.
 I get an error with f2py

 with exit status 1

 The only difference I see is that this module use $ for line continuation.

 Do you think this is the issue?

 I have uploaded the fortran file for you to try
