Modified files:
usr.bin/f2c f2c.h
Log:
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.
