I can confirm that PPL now builds successfully for i686-mingw32 host.  The 
next problem is that CLooG (the tarball in the infrastructure directory) 
doesn't appear portable to this system (in the secondary platforms list 
for 4.4 and 4.5); I get:

source/program.c:42:27: error: sys/resource.h: No such file or directory
...
source/program.c:674: error: 'RUSAGE_SELF' undeclared (first use in this function)
...

This does not appear to be a cross build problem; it appears this file 
uses this header, not available on MinGW, unconditionally with no 
configure checks.
