Replace 'long int' with 'int' for Alpha.

This change should have no effect on i386.

Quote from http://www.netlib.org/f2c/readme:

NOTE:   f2c.h defines several types, e.g., real, integer, doublereal.
        The definitions in f2c.h are suitable for most machines, but if
        your machine has sizeof(double) > 2*sizeof(long), you may need
        to adjust f2c.h appropriately.  f2c assumes
                sizeof(doublecomplex) = 2*sizeof(doublereal)
                sizeof(doublereal) = sizeof(complex)
                sizeof(doublereal) = 2*sizeof(real)
                sizeof(real) = sizeof(integer)
                sizeof(real) = sizeof(logical)
                sizeof(real) = 2*sizeof(shortint)
        EQUIVALENCEs may not be translated correctly if these
        assumptions are violated.

        On machines, such as those using a DEC Alpha processor, on
        which sizeof(short) == 2, sizeof(int) == sizeof(float) == 4,
        and sizeof(long) == sizeof(double) == 8, it suffices to
        modify f2c.h by removing the first occurrence of "long "
        on each line containing "long ", e.g., by issuing the
        commands
                mv f2c.h f2c.h0
                sed 's/long //' f2c.h0 >f2c.h
        On such machines, one can enable INTEGER*8 by uncommenting
        the typedef of longint in f2c.h, so it reads
                typedef long longint;
        by compiling libI77 with -DAllow_TYQUAD, and by adjusting
        libF77/makefile as described in libF77/README.

I found the reason why f77 so offen dies on alpha. Here is a fix.
"Const" is a union of int and double.
If nelt->constblock.Const.ci > 0 then it trys to evaluate it as double
and floating point exception occurs.

During compilation of a Fortran program f2c/f77 will spew the

1998-07-24T07:13:57+00:00

name of entry points, functions, subroutines, and program to
stderr error.  The enclosed patches do 3 things:

     (1) Silenced the output to stderr.
     (2) Added a -v option to f2c and f77.  This will turn on a verbose
         mode, and dumps quite a bit of stuff to stderr.
     (3) Updated the f2c man page.

Fixed `make -jN' for large N. Just put all generated headers in SRCS.

Use the same format for the "expect N shift reduce conflicts" message

Fixed some minor formatting problems to silence manck some more.

1996-02-12T01:20:38+00:00

Corrected some bogus cross references to man pages that we don't/won't
have and either deleted them, or found a more appropriate man page
that we do have.  Various other minor changes to silence manck.

Manck is currently down to about 200 lines of errors, down from
the 500 - 600+ when I started all this.
