Warn About Implicit Conversions

g77 needs a -Wpromotions option to warn if source code appears to expect automatic, silent, and somewhat dangerous compiler-assisted conversion of REAL(KIND=1) constants to REAL(KIND=2) based on context.

For example, it would warn about cases like this:

DOUBLE PRECISION FOO
PARAMETER (TZPHI = 9.435784839284958)
FOO = TZPHI * 3D0
