The problem is a hack in gmp's configure.ac which is incompatible with
newer libtool versions.  As I've been working on 64bit packages, these
are now in Ports git:

http://cygwin-ports.git.sourceforge.net/git/gitweb.cgi?p=cygwin-ports/gmp;a=tree
http://cygwin-ports.git.sourceforge.net/git/gitweb.cgi?p=cygwin-ports/mpfr;;a=tree
http://cygwin-ports.git.sourceforge.net/git/gitweb.cgi?p=cygwin-ports/libmpc;a=tree

ppl and cloog-ppl should be straight-forward, but for 4.8 we instead
need isl and cloog-isl, and the two cloog's aren't fully
parallel-installable OOTB.  To work around that, I suggest both be built
with --includedir=/usr/include/${NAME}, then we can pass
--with-cloog-include to GCC depending on the version being built.

HTH,


Yaakov
