I have a guess, but it is weird,

I couldn't find any BEGIN(fixed_fmt) for the <fixed_fmt> start condition
(whereas there is for <str_sq> or <str_dq>)
in
http://public.kitware.com/cgi-bin/viewcvs.cgi/Source/cmDependsFortranLexer.in.l?root=CMake&view=markup
which makes me think that ALL <fixed_fmt> rules in the lexer are
currently ignored
because the start condition never gets activated.
i.e. there should be some code that's tell the lexer that it is lexing
a fixed format file.
Note that this is the same for <free_fmt> but this start condition is not used
in any rules of the lexer, it is only declared at the same line as the
<fixed_fmt> ??
I'm no flex/lex expert thus take my guess with care.
