Building Open MPI 1.0.1 on a PowerMac running OS X 10.4.4 using
1) Apple gnu compilers from Xcode 2.2.1
2) fink-installed g77
3) latest g95 "G95 (GCC 4.0.1 (g95!) Jan 23 2006)"
  (the binary from G95 Home)

setenv F77 g77
setenv FC g95

In the G95 section of the configure I get

checking size of FORTRAN integer(selected_int_kind(2))... unknown
configure: WARNING: *** Problem running configure test!

Gzipped config.log attached.

If I change to the older Fink g95 "G95 (GCC 4.0.2 (g95!) Dec 19
2005)" I don't see this problem
