regex: don't assume uint64_t or uint32_t
* lib/regcomp.c (init_word_char): Don't assume that the types
uint64_t and uint32_t exist. The C standard doesn't guarantee
them, and on some 32-bit compilers there is no uint64_t.
Problem reported by Gianluigi Tiesi in
<http://lists.gnu.org/archive/html/bug-gnulib/2012-03/msg00154.html>.
