Howdy Ruben!

I am now building the netCDF library on cygwin, with target=mingw32. This is 
not quite the same as what you were trying to do, but close.

Since your email, the architecture of the library has changed a lot. The v2i.c 
file is now in the libdispatch directory, and I'm not sure that it needs to 
include nc.h any more.

As for the line ending problem, I am not sure what I should do. Do you have any 
suggestions?

Could you try this with the daily snapshot release?

Thanks,
