Included here are binaries for Windows.
The pre-compiled library and hyphenation patterns were stolen from msys2.
See https://packages.msys2.org/package/mingw-w64-x86_64-hyphen?repo=mingw64,
and https://packages.msys2.org/package/mingw-w64-x86_64-hyphen-en?repo=mingw64.
Those packages are re-distributed here without modification in "pkg".
The license included with the pre-compiled binary is plainly included here too.
The otherwise compilation was done by means of mingw-w64.
tcc would have been used instead if it supported linking to 'ar' archives.
