Hi Bert - a few comments:

1) This won't work properly unless there is a way to export the fact 
that NE_LFS is defined in the API on Win32 - otherwise the app building 
against neon has no way to tell.

2) Doing this by default is a backwards-incompatible ABI break, which 
I'd rather avoid.

I'd suggest doing something like:

a) have neon.mak create a src/ne_w32conf.h or similar file, which contains
the #define NE_LFS, and install this along with the other headers

b) have ne_defs.h conditionally #include src/ne_w32conf.h on Windows to 
pick up the types.

Regards, Joe
