That's "generator requirement" --- a set of properties which are needed to
even try running the generator. Since you have not defined the 'gfortran'
toolset (and I think we decided fortan toolset should be orthogonal from
ordinary C++ toolset), the generator is never run. V2 unhelpfully allows
sources which are not consumed in any way.
There are two questions:
1. Why can't we issue a warning that .f file is not used? We used to issue
such warning but this ended up being a mess. The warning was issued on some
valid uses and implementation was complex.
2. Why "generator requirements" are not documented? Hell knows -- I completely
forgot about them. I'll fix that asap.
