[Mingw-users] fortran link failures

[Ian D. G. <ga...@sf...>]

Using MinGW-3.1.0-1 out of the box, installed by windows install 
program, fortran programs will compile but not link. The link stage of 
gcc fails with undefined references to s_wsle, do_lio, e_wsle, s_stop 
and winMain@16.

This error can be cured by linking with libg2c and libfrtbegin. As far 
as I can see, this is not documented anywhere, and is not in the faq. 
It would be nice if it were documented, so new users can find it more 
easily than I did.

It would be even nicer if it just worked out of the box. This can be 
done by modifying the specs file appropriately. I have a specs file 
which appears to work for fortran and doesn't break C. (Haven't tested 
C++). I'd be happy to contribute this to the project, if someone tells 
me where to send it.
