Currently, fortran code compiled with g77 (gcc-3.x) can only use a maximum of
100
file units due to a hard coded limit
#define MXUNIT 100
in gcc-3.x.x/libf2c/libI77/fio.h (see "info g77" and MXUNIT for more details).
The quantum chemistry code sci-chemistry/gamess which I am maintaining
has recently introduced new functionality which requires access to more
than 100 file units (300, to be precise) and these routines, therefore, don't
run properly with our current g77 setup. Future development of the code
will likely increase the number of routines that will have to have access to
larger file units.
I would therefore like to ask if it would be possible to increase the number of
available file units in our g77 installs and I've attached a patch that
accomplishes
this and works fine on my system (pentium 4m, gcc-3.4.4-r1).
Unfortunately, I don't know the internals of gcc very well and can't judge if
this patch
introduces any unpleasant side effects. If not, I would be very grateful if you
could
consider including this change.
