I'm guessing the difference is that gcc4's system includes don't use  
the filename "features.h", whereas 3.x does. That's what makes the  
build fail with gcc3 (see below).

AAUI, it does .... but the problem is that icu's Features.h is then  
found when a gcc3 system header wants to include gcc3's features.h.  
That's what breaks the build (I think, from the reports -- haven't yet  
had time to try setting up a cygwin environment of my own).

It's probably fine, but I'll look again.... I think it may or may not  
be needed depending how the compiler feels about type  
compatibility.... don't recall the details offhand.

Right, unless the libs get different names under cygwin and the  
makefile is depending on the wrong (Unixish) name. Look in Work/libs/ 
icu-xetex/lib to see what did get built (if anything). If nothing,  
then look at the configure and make output for the icu-xetex dir to  
try and see where it's failing. Maybe icu build on cygwin is broken?  
I'm sure it's not one of their reference platforms. Try the icu- 
support mailing list if necessary.
