While working on the dragonegg plugin I noticed that the Fortran front-end
declares frexp with the parameters the wrong way round. Instead of
double frexp(double x, int *exp);
it is declared as
double frexp(int *exp, double x);
This is fairly harmless but might as well be fixed, so here is a patch (as far
as I can see fntype[4] is only used in declaring the frexp family of functions).
Bootstraps and has no impact on the Fortran testsuite (tested on mainline). OK
to apply on mainline and the 4.5 and 4.6 branches?
Proposed fortran/Changelog entry:
2011-03-30 Duncan Sands <baldrick@free.fr>
* f95-lang.c (build_builtin_fntypes): Swap frexp parameter types.
