In this version I have it in there, but set it to undef. This way
configure (MinGW), meson (MinGW or MSVC), and Solution.pm all agree.
This version passes on CI (not quite sure what I screwed up before).
To restate the problem I am solving with this Solution.pm change +
associated changes in the C: configure+MinGW disabled the libc
provider completely before. With this patch that is fixed, and that
forced me to address the inconsistency (because if you have the libc
provider but no _l functions, you hit uselocale() code paths that
Windows can't do). It was a bug, really, but I don't plan to
back-patch anything (nobody really uses configure+MinGW builds AFAIK,
they exist purely as a developer [in]convenience). But that explains
why I needed to make a change.
Thinking about how to bring this all into "normal" form -- where
HAVE_XXX means "system defines XXX", not "system defines XXX || we
define a replacement" -- leads to the attached. Do you like this one?
