Right, because it's not supported.  It's probably not supposed to be in
there.

It doesn't have a libc in the usual sense.

rexec and recv are both socket functions.  I _think_ that recv might be a
function in wsock32.dll (try running nm or strings on it and/or
winsock.dll).  I _think_ the functions that need wrappers and that aren't
in the Win32 api are included in the "libc" a.k.a. libcygwin.a/cygwin.dll.
I _think_ all the functions that are copied straight over from Win32 dlls
have their own .a libs.
