One item I forgot to discuss in the original email was the change
in intrinsic.c to split generic "real" into individual generics.
Originally, intrinsic.c grouped real, float, dfloat, sngl, realpart
and if -fdec is present float[ijk] under the generic "real".
real is specified to have 2 arguments where the second one is 
optional.  All other intrinsic names take a single argument.  If
on wrote "real(1.2324, 4)", then gfc_check_real() is called to do
check the arguments.  This is good.  However, if one wrote 
"real(1.234)", then gfc_check_float() is call.  The Fortran standard
specifies the float takes a default integer as an argument, and I
while real can a numeric type.  By splitting each intrinsic into 
its own generic, gfc_check_real is now called for "real(1.234)"
as good thing!
