I don't see any reference to a regex lib.  But maybe you removed it already?

Good.

The --disable-speller option is enough to get nano to build on Mingw32?
You don't pass any other options?  That would be strange, because the
linter uses fork() too and it doesn't get disabled by --disable-speller.

In your build script you pass --disable-justify to ./configure.  Is there
any specific reason that you pass this option?  And if your nano does not
do any justification, shouldn't you mention this in the README?
