Comment #4 on issue 1827 by percival.music.ca: GUB failure for  
darwin-x86::cross/gcc target

I wonder if this one is relevant?
%% cygwin::cross/gcc: add comment about system's dependency libmpfr-dev.

I've got libmpfr1ldbl installed, but not libmpfr-dev ?  There's no mention  
of mpfr in the README.
