Sorry for the naive question, I don't know Windows programming.

Do we really need this external code?
Why RtlIsNameInExpression from Windows cannot be used?

The general reason not to use Win32 API for globbing is poorly documented
contract: what are the exact matching rules? They're definitely incompatible
with fnmatch(3). IMO small external code is better than unknown behavior.

RtlIsNameInExpression is an internal call for drivers and services with a
cumbersome API. PathMatchSpecA is the user-mode interface, but see above.

I will agree with Dmitry here. The fnmatch external code is shipping, 
production quality code. So it's better to use it than writing something 
new.

fnmatch is required to change the log level of logs
specified with a globbing pattern.

I think it would be nicer to introduce fnmatch first,
and state in the other patch that logging is supported on Windows.

Titles would be:
eal/windows: add fnmatch implementation
log: support on Windows
