That's interesting: I just had the same experience with yesterday's CVS 
snapshot (12 June), trying to test dell1600n_net on WinXP/cygwin.

The problem first shows up in some build messages which appear to come 
from libtool saying that a compatible version of phtreads could not be 
found to link dynamically and so only a static version of the backend 
would be built.  The dll backend clearly can't load this!  I will try to 
dig deeper this evening.

On a different note, when i unpacked the snapshot and just did 
"./configure && make" it failed to compile like:

coolscan.c: In function `attach_scanner':
coolscan.c:2096: warning: implicit declaration of function `strdup'
coolscan.c:2096: warning: assignment makes pointer from integer without a cast
coolscan.c: In function `reader_process':
coolscan.c:2574: warning: implicit declaration of function `fdopen'
coolscan.c:2574: warning: assignment makes pointer from integer without a cast
coolscan.c:2593: error: structure has no member named `sa_handler'
make[1]: *** [coolscan.lo] Error 1
make[1]: Leaving directory `/cygdrive/c/downloads/sane-backends/backend'
make: *** [all-recursive] Error 1

I'm not at home now so I can't tell you the exact version of gcc but it is 
whatever is the newest cygwin version.  (I updated cygwin before 
starting.)

I got around this by just compiling the backends I needed but I guess this 
should be addressed prior to the release.

cheers,
Jon
