[svn-r18696] I added a macro definition if the system is Cygwin in configure.in. This macro is used to skip

the data conversion test from unsigned long long to long double.  The GCC on Cygwin seems to 
have rounding problem when doing conversion from unsigned long long to long double (Please bug
#1813).

Tested on jam.  I'll test it on Cygwin after this checkin.
