"Note:        This syntax checker uses gfortran with the option -fsyntax-only
"             to check for errors and warnings. Additional flags may be
"             supplied through both local and global variables,
"               b:syntastic_fortran_flags,
"               g:syntastic_fortran_flags.
"             This is particularly useful when the source requires module files
"             in order to compile (that is when it needs modules defined in
"             separate files).
