Will do.

The prototype warnings have been there foreever.  On hpux, the error
appears as a result of your change:

../../../gcc/libgfortran/intrinsics/c99_functions.c: In function 'casin':
../../../gcc/libgfortran/intrinsics/c99_functions.c:1433:11: error: 'I'
undeclared (first use in this function)
