[bug #65537] Werrors from intprops-internal.h with gcc 8.3.0

[Paul Eggert]

Follow-up Comment #5, bug #65537 (group make):

[comment #0 original submission:]

> I don't understand the macro guard there.  Why would Paul Eggert want to
avoid using the pragma in the half-open region between gcc 4.4 and gcc 5,
while using it for the half-open region from gcc 4.0 to gcc 4.4?

If you're talking about this code:

/* Pacify GCC 13.2 in some calls to _GL_EXPR_SIGNED.  */
#if defined __GNUC__ && 4 < __GNUC__ + (3 <= __GNUC_MINOR__)
# pragma GCC diagnostic ignored "-Wtype-limits"
#endif


This uses the pragma in GCC 4.3 and later because GCC 4.2 and earlier doesn't
support "#pragma GCC diagnostic ignored" and issues a diagnostic about it.

With the above code in place, you shouldn't need to put -Wno-error=type-limits
into MAKE_CFLAGS. If you're still getting a diagnostic with the above code in
place and with MAKE_CFLAGS unchanged from Git, please investigate why the
above code doesn't suppress -Wtype-limits.
