No.  The problem isn't the definition of off_t but the dependency of
regoff_t from off_t.  This results in changing the size of regoff_t
*inside* of Cygwin with 1.5.0 since now __CYGWIN_USE_BIG_TYPES__ is
defined and off_t is 64 bit.  The solution is either to decouple
regoff_t from off_t and use _off_t instead, so regoff_t is always
32 bit or to go the hard way and define __regoff32_t and __regoff64_t
and 32 as well as 64 bit entry points for the external regex functions.

I'm tending to keep it 32 bit.
