I've found that the default options of gcc and g77 on alpha produce an
executable that suffers from floating exceptions. There seems to be a
problem with the configure scripts that prevents the --with-f77 option
working correctly. The configure script tests that f77 is running by
attempting to compile and link a dummy program - the link step seems
broken on the alpha (it doesn't like the command 

f77 -o conftest conftest.f -L/usr/local/lib

The command works fine without the -L switch.


my workaround was to remove $LIBS from the line
ac_link='${F77-f77} -o conftest${ac_exeext} $FFLAGS $LDFLAGS
conftest.$ac_ext $L
IBS 1>&5'

but a better alternative may be to just use the fortran compiler to
produce an object file rather than an executable.

R configured using the following options passes "make test"
