Hi all,

i can't query the LIB environment variable from C++ code, compiled with 
g++, with GetEnvironmentVariable, as demonstrated in the appended, small 
example program. Other variables (e.g. PATH could be retrieved without 
problems). The example program queries LIB and prints it out. The output 
i received is an empty string.

I've installed the current cygwin version.

If i go back with the cygwin dll to 1.5.18-1 it worked without 
problems!!! But than a lot of other cygwin tools don't worked.

The problem occured originally on compiling the Coin3D library. They are 
using a cygwin compiled wrapper program (wrapmsvc.exe), which is 
querying the LIB variable and failed.

Many thanks for any hints

Kai
