I am (as you may well know) extremely fortran averse.  However, a
researcher in our department has recently asked what the current limits
are on the size of an array in modern fortran(s) under linux.  I suppose
he'd like an answer for both 32 and 64 bit systems.  From what I have
been able to google out, it looks like the answer is 2^31 bytes in 32
bit systems and as big as the hardware permits less maybe a GB in 64 bit
systems.  Is this correct?  Any fortran experts out there?  I'd be happy
for answers for more than one compiler, of course -- I'd guess that e.g.
pathscale might have a greater capacity than e.g. gfortran than g77
legacy...
