Remember build libraries and includes come in ...-devel packages - often
lib...-devel packages.
Package search online or with:

$ cygcheck -p nl_types.h
Found 2 matches for nl_types.h
libcatgets-devel-1.1-2 - libcatgets-devel: catgets message catalog API;
development (installed binaries and support files)
man-pages-posix-2013-a-1 - man-pages-posix: POSIX manual pages (installed
binaries and support files)

Check the package contents online from the package search results or download
and list:

$ tar -tf
mirror/x86_64/release/catgets/libcatgets-devel/libcatgets-devel-1.1-2.tar.bz2
