Okay, then I'm gonna assume that you are linking against a kernel that you
built yourself, and not the "official" cygwin kernel that cgf built
(otherwise, the following applies to him):
You ought rebuild your cross-binutils from the binutils-20011002-1-src as
distributed from the cygwin mirrors.
Recent binutils (post-20010802) add special autoimport-support thunks to
the dll's that they create. These are used to create a lookup table for
the variable exports, by fooling the windows runtime loader. (I don't
understand the whole thing, but it's a neat concept.)
Anyway, the *DLL* as well as your client app need to be built using a
recent binutils, in order for the auto-import thing to work properly.
Of course, with the cygwin1.dll, auto-import shouldn't be necessary.
__progname *ought* to be declared (with appropriate __declspec() markings)
in some header file somewhere, so that's a cygwin bug.
