building dll with the use of gcc-cross-comp. and cygwin

[Fredriksson, Johan]

I'm trying to build a dll on the solaris platform with use of
gcc-cross-compiler and cygwin.
The problem is that if I use WINAPI when I create my dll-entry-point, 
as I should according to cygwin, the compiler or linker is not able to
interpret windows.h. 
In the second atemt I created i an Entry-point without 
using WINAPI...just a function returning int.
But when I use that I can't reach any of the functions inside my dll. 

My questions are:

1. Am I not able to use gcc-cross-compiler and cygwin to build a dll on the
solaris platform?

2. Why am I forced to use WINAPI when I create my Entry-point? All the
examples I've seen use that?
