Intrinsics in `PARAMETER' Statements
------------------------------------

   `g77' doesn't allow intrinsics in `PARAMETER' statements.  This
feature is considered to be absolutely vital, even though it is not
standard-conforming, and is scheduled for version 0.6.

   Related to this, `g77' doesn't allow non-integral exponentiation in
`PARAMETER' statements, such as `PARAMETER (R=2**.25)'.  It is unlikely
`g77' will ever support this feature, as doing it properly requires
complete emulation of a target computer's floating-point facilities when
building `g77' as a cross-compiler.  But, if the `gcc' back end is
enhanced to provide such a facility, `g77' will likely use that facility
in implementing this feature soon afterwards.
