[PR fortran/89286, patch] Intrinsic sign and GNU Extension for review

[Mark Eggleston]

For review.

The attached patch and change logs is to treat SIGN in the same way as 
DIM, MOD and MODULO in regard to the GNU extension i.e. when -std=gnu.

The change logs have no dates, they can be added when the patch is 
committed provided this patch is accepted.

Note: I do not have write access to svn.

regards,

Mark
