COMSPEC environment variable missing

[ib at wupperonline dot de (Ingo Brueckl)]

Hi.

I'm using the 20051227-snapshot of cygwin1.dll. This is my Windows 98SE
environment as told by the 'set' command:

  TMP=C:\WINDOWS\TEMP
  TEMP=C:\WINDOWS\TEMP
  PROMPT=$p$g
  winbootdir=C:\WINDOWS
  PATH=C:\WINDOWS;C:\WINDOWS\COMMAND
  COMSPEC=C:\WINDOWS\COMMAND.COM
  DIRCMD=/o:gne
  windir=C:\WINDOWS
  BLASTER=A220 I5 D1 H5 P330 T6
  CMDLINE=myset

In a cygwin program, there is no COMSPEC environment variable. I get NULL
when using getenv().

In order to check my cygwin environment, I wrote the following program:

  #include <stdio.h>
  #include <unistd.h>

  int main()
  {
    int i;

    for(i = 0;; i++)
      if (environ[i]) puts(environ[i]);
      else break;

    return 0;
  }

which returns:

  !C:=C:\WINDOWS\TEMP
  TMP=/tmp
  TEMP=/tmp
  PROMPT=$p$g
  WINBOOTDIR=C:\WINDOWS
  PATH=/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/COMMAND
  DIRCMD=/o:gne
  WINDIR=C:\WINDOWS
  BLASTER=A220 I5 D1 H5 P330 T6
  CMDLINE=myset
  PATH=/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/COMMAND
  TERM=cygwin
  HOME=/home/ib

Indeed, COMSPEC is missing, and PATH is twice.

A bug?

Ingo
