Node: Warn About Implicit Conversions, Next: Invalid Use of Hollerith Constant, Previous: Better Pedantic Compilation, Up: Missing Features
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
