ce to work with the
first compiler it finds, e.g. <code>g77</code>.  To configure for a different, incompatible Fortran compiler
<code>foobar</code>, use <code>./configure F77=foobar</code> when installing FFTW.  (In the case of <code>g77</code>, however, FFTW 3.x also includes an extra set of
Fortran-callable routines with one less underscore at the end of
identifiers, which should cover most other Fortran compilers on Linux
at least.)
