I'm aware of that, but newlib-cygwin is a git repo since 2016.

Not using git-formatted patches moves the onus for correct author
information as well as correct content of the commit message from the
author to the commiter.

So I hope it's ok to request git-formated patches.  A detailed commit
message doesn't hurt either.

Shouldn't this be changed to size_t?

Shouldn't unsigned long be changed to uintptr_t here, too?

And size_t here?


Thanks,
