g77 compiler option for forcing constants to be real*8

[Michael Olberg <michael.olberg@chalmers.se>]

Hi,

Does anybody on this list happen to know the compiler option for g77 to 
compile all constants as real*8?

E.g. in a statement like

c = 1./a

the 1. should be read as if it had been typed as 1.0d0. Sun's and HP's 
compilers usually have compiler flags for that.

regards
Michael
