make failure on libuv AF_LINK | R, Cygwin

While installing packages in R as 

install.packages('fs')
#the make requirement fails at the libuv_la-bsd-ifaddrs.lo

$ make[1]: *** [Makefile:2258: src/unix/libuv_la-bsd-ifaddrs.lo] Error 1

Cygwin setup includes libuv, libuv-devel, libvirt, libvirt-devel

Am i missing something or is there something i need to patch for this?

the fs package is embedding a old version of libuv (1.18) the current Cygwin shared lib is based on 1.24 . The error you see was solved by a proper #ifdef in later versions.

What I do not understand is why fs is embedding libuv instead of using the present version.

So you can ping upstream to upgrade or you can replace the current version with latest vesion of libuv embedded and created a customer version of the fs source package.
