Comment (by fhgwright):

 I admit I don't think I ever tested anything with `-std=c90`, so it makes
 sense that I never saw that.  Presumably `gcc14` is engaging in its
 typical obnoxiousness of acting like `-pedantic` even when `-pedantic`
 isn't specified, with the effect of failing to recognize `inline` as a
 keyword in the `-std=c90` case.

 Indeed the motivation for the `-std=c90` is highly unclear.  Usually, such
 options are used to force a ''minimum'' language standard, only to
 sometimes cause trouble by forcing a ''maximum'' standard (as in this
 case).  But I can't imagine what compiler would need to be told `-std=c90`
 as a ''minimum''.  It should be completely equivalent to `-std=c89`, and
 the only thing earlier than that would be K&R C, which is almost certainly
 not the default, if it's provided at all.

 Except for being related to compiler options rather than feature flags,
 this is a similar issue to #72406.
