[CMake] Compiling fortran

[Juan Sanchez]

Hi Bill,

I wouldn't mind taking a stab at it.

It would be easy enough to tell lex to drop any line starting with a
comment character.  Something along the lines of:

^[cC].* {}

There seems to be a line in the lexer that does this, but it doesn't
appear that that the start condition, fixed_fmt, is ever activated.

<fixed_fmt>^[cC*dD].*\n { return EOSTMT; } /* empty lines */

Do you have any info about how to make submissions and getting the
latest CVS?

Juan
