There is no SSE register source operand. Probably "Only register
source operand is allowed."

This change is safe to make now (in stage 4), because the constructors

Although there is no good use for stack> or similar
types with a mismatched value_type, it's possible somebody is doing that
and getting away with it currently. This patch only enforces the new
requirement for C++17 and later. During stage 1 we should consider
enforcing it for C++11 and C++14.

Enabling of -fdec-include is missing from list of options enabled by
-fdec. When rendered as a PDF some lines are too long in the list of
options controlling Fortran dialect and in the list of options to
request or suppress errors and warnings.
