You're right. Sorry for the confusion.

...and Andy's correct. This is a (long-standing) problem with the
-mno-cygwin mode: it tends to "mix" cygwin libs in /usr/lib and the
"native" ones in /usr/lib/w32api/ together (which is very bad). The
cross compiler setups do not have this problem (but, AFAIK, the
mingw64-* based cross compilers aren't official supported for building
setup.exe...which means we(*) need to get off the stick and publish a
mingw.org-based cross compiler soon).
If you want to use gcc-3, then the two workarounds are, as Andy
suggests, to uninstall libuuid-devel, or to modify the
Makefile[|.in|.am] that specifies -luuid and explicitly refer to
(*) For various values of "we".
