Build failure due to conflict between UUID.DLL and libuuid

[GoogleCodeExporter]

What steps will reproduce the problem?
1. download & untar mintty-0.8.3-src.tar.bz2
2. in the source directory, launch 'make'

What is the expected output? What do you see instead?
I expect that make can build mintty.exe.
But it fails on the link step : undefined reference to `_IID_IUnknown'

What versions of mintty, Cygwin/MSYS, and Windows are you using?
version 8.3, compilation using cygwin 1.7

Please provide any additional information below.

maybe missing additional library ? (symbols _IID_IUnknown & _IID_IDropTarget 
are unresolved)

Works fine for me, both with gcc-3 and gcc-4. Those two are defined in 
/usr/lib/w32api/libuuid.a apparently, and that's on the link line.

There've been no obviously relevant recent changes, and there's always a fair 
number of source downloads, without any problems having been reported so far. 
So that suggests a local issue.

Are you using an up-to-date Cygwin 1.7? Perhaps try reinstalling w32api? 
Shuffle the library order in the ld_opts line in the makefile? Add -lshell32 
(since grep finds IID_IDropTarget in that library too)?

it's a conflict beetween packages w32api and libuuid-devel.
there are 2 different version of libuuid

$ find /lib/ -name \*uuid\*a
/lib/libuuid.a
/lib/libuuid.dll.a
/lib/libuuid.la
/lib/w32api/libuuid.a

there is a thread on cygwin mailinglist about this : 
http://www.mail-archive.com/cygwin@cygwin.com/msg106029.html

temporary workaround : uninstall libuuid-devel !

Thanks very much for tracking that down. Looks like the problem is not going to 
go away: http://cygwin.com/ml/cygwin/2010-06/msg00601.html. Sigh. So I better 
work around it in the makefile. r1025 on trunk.
