work-around for IRIX 6.2 64-bit library bug

[Ralf W. Grosse-Kunstleve]

Hi!

It turned out that under certain circumstances, xplor triggers a bug
on the IRIX 6.2 64-bit Fortran runtime library. If you experience
crashes, try:

setenv FORTRAN_OPENED_UNITS 1000

The best way to do this permanently, is to insert a few lines in the
"# use mips4 on r8k and r10k" block in $COMS/ulogin.com. See below.

This "fix" will be included in the next X-PLOR(online) release.

Ralf



# use mips4 on r8k and r10k
if ( $CPU =~ R8000 || $CPU =~ R10000 ) then
   set MIPSFLAG = '-mips4'
   set LFASTM = '-lfastm'
   set OPTFLAG = "-O2 -WK,-o=1,-so=0 -OPT:roundoff=3:IEEE_arithmetic=3:fold_arith_limit=2000 -TENV:X=3"

   # work-around for IRIX 6.2 problems
   if ( $OSMAJOR == 6 && $OSMINOR == 2 ) then
     setenv FORTRAN_OPENED_UNITS 1000
   endif
