Microsoft recently announced version 5.1 of their FORTRAN compiler, with
extensive Windows support, including the use of extended memory.  To quote
from their brochure:

   "Access all virtual memory on a PC with an 80386 or higher processor,
   up to 64 megabytes.

   Access all extended memory on a PC with an 80286 processor."

Of course, starting with version 4.1, Microsoft's FORTRAN compiler also ran
under OS/2, which gave you access to 16 megabytes of memory.  Which vendors
will support the 32-bit version of OS/2 (which has a 4 gigabyte flat memory
architecture) remains to be seen.
