A test needs to be put in the .l file to determine whether fixed or free format fortran is being used.

All Fortran compilers I know of use two methods to select between free 
form or fixed form source:
- The extension of the file (.f and .for are used for fixed form, .f90 
for free form)
- A command-line option which tells the compiler to ignore the first 
rule and accept
  the source file as either fixed form or free form.

That said, similar rules could be adopted for CMake. (Of course the 
command-line option
makes it a bit awkward, but then anybody who wants to use that will 
somehow have
to specify that he/she wants that anyway)
