f2c calling conventions require that a scalar default REAL function actually returns the C type double. Our current implementation makes the function symbol's backend_decl of type double, which in the case of no explicit RESULT variable leads to all kinds of type mismatches. This patch fixes this, by only making the function REAL*8, not the RESULT variable, and then converting the result variable to REAL*8 when passing it to the function result.Built and tested on i386-darwin, this passes the testsuite except for the failures which are due to PR29516. Ok?

OK.Note, this bootstrapped and passed regression testing on x86_64-*-freebsd.

Tobi, this might be considered a regression with respect to g77 (although I believe g77 did not support RESULT). I'll leave it to your discretion whether to backport to the 4.2 branch.
