Subject: [Boost-users] Boost forces Cygwin build to be 32-bit, even when it shouldn't

I'm having trouble building boost under Cygwin. I've installed the 64 bit
version of Cygwin and all programs are compiled as 64 bit.
Yet, for some reason, the header ./boost/python/detail/wrap_python.hpp
defines SIZEOF_LONG to be 4 when __CYGWIN__ is defined, which is only valid
for a 32-bit system. This signals an error check in a python header, and
the build fails.
Why does this #define exist? Can we get rid of it?
