* decl.c (match_old_style_init): Use a clearer error message.
* expr.c (gfc_check_assign): Update BOZ checking to provide a stricter
adherence to the Fortran standard. Use gfc_invalid_boz () to
relax errors into warnings.
* gfortran.h (gfc_isym_id): Add new ids GFC_ISYM_DFLOAT,
GFC_ISYM_FLOAT, GFC_ISYM_REALPART, and GFC_ISYM_SNGL
* intrinsic.c (add_functions): Use new ids to split REAL generic into
REAL, FLOAT, DFLOAT, SNGL, and REALPART generics.
(gfc_intrinsic_func_interface): Allow new intrinsics in an
initialization expression
* resolve.c (resolve_operator): Deal with BOZ as operands.
Use gfc_invalid_boz to allow for errors or warnings via the
-fallow-invalid-boz option. A BOZ cannot be an operand to an
unary operator. Both operands of a binary operator cannot be BOZ.
For binary operators, convert a BOZ operand into the type and
kind of the other operand for REAL or INTEGER operand.
* trans-intrinsic.c: Use new ids to cause conversions to happen.
