POLL now accepts more than one descriptor and returns information about pollable descriptors. SMPHRTRYDECR now takes a timeout value instead of returning when a semaphore cannot by decremented.
Signal handlers are fixed to avoid spurious and very rare deadlocks. Pari is upgraded. CFLAGS is forced for tools/file (-O2 -g) to avoid a mmap() error. Giac, gmp, and mpfr have been upgraded.
