Thanks, it looks good to me; please install into the master branch

What happens if a source file that uses pcase is compiled on a 64-bit
machine that has wide fixnums, and is then loaded and run on a 32-bit
machine that has narrow fixnums? Will this pcase code still work? And if
not, are there similar bugs elsewhere in the pcase code?
