GCC 3.4.3: Cygwin -> arm-wince-pe

Greetings, everybody.
I used to use PocketGCC for compiling (console) apps for arm-wince-pe
but was dissatisfied because of small memory amount (or bad
management) on my PocketPC. Therefore, I tried to build a
i686-pc-cygiwn -> arm-wince-pe cross compiler. Everything was
(finally) built ok, but without _any_ header files as I think, so I
took the files posted somewhere in the group (lost the link, but it
was some TGZ file). Now, I get the following message while compiling
Hello World:

/usr/local/lib/gcc/arm-wince-pe/3.4.3/../../../../arm-wince-pe/bin/ld:
warning: cannot find entry symbol _mainCRTStartup; defaulting to 00011000

The app is built, but doesn't work (produces no error messages
though). What's wrong with mainCRTStartup?
