Subject: Incorrect resolution of COMSPEC environment variable on WinNT

Is this a bug or am I missing something?

With the following code:


main()
{
    char *comspec_value = getenv("COMSPEC");
    printf("%s\n", comspec_value);
}

When compiled with DJGPP's gcc on WinNT 4, the output is:

C:\WINNT\SYSTEM32\COMMAND.COM

The trouble is that on NT 4, (and I have verified this in my shell) COMSPEC is 
set to c:\winnt\system32\cmd.exe.  The correct value is output when compiled 
under several other compilers.

If anyone sees a mistake, or if it is a bug, knows of a workaround for this, 
I'd love to hear it.  Alternatively, (This may be a newbie question, but I 
can't find any info in the docs on this) if there is a way to identify the 
operating system the program is running under, then I suppose I could hardcode 
in cmd.exe on WinNT.

Thanks in advance,

-Jon
