Querying the LIB environment (from g++) don't work with current cygwin.dll (1.5.19-4)

[Kai Benndorf <ben_1 at pad dot zuken dot de>]

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
#include <iostream>

#include <Windows.h>

int main( void )
{
  const int bSize = 32657;
  char buffer[bSize];
  int resultsize = GetEnvironmentVariable("PATH", buffer, bSize);
  std::cout << "PATH: " << buffer << std::endl;
  buffer[0] = 0;
  resultsize = GetEnvironmentVariable("LIB", buffer, bSize);
  std::cout << "LIB: " << buffer << std::endl;
}
