Win32 gawk vs. Unix awk

gibsonca has asked for the wisdom of the Perl Monks concerning the following question:

Ultimately I want to convert about 5 gawk/awk scripts to perl, but right now just trying to understand what I percieve as a difference between gawk (version 3.1.6) and sun unix awk. (Using or not using perl does not affect the problem.)

  $cmd = "gawk -f D:\\tools\\scan_tdf.awk 
           corrtype=ada 
           FileSuffix=_pkg 
           TDFname=sys_mma_pfd_gmeter.tdf
           PrefixFile=d:\\tools\\PrefixFile
           BusNamesFile=d:\\data\\ssi_BusNames 
           VAXPATH=NONE
           DIRPATH=def";

  print "cmd is $cmd \n";
  $sts = system($cmd);

On the sun unix side the variables are getting passed through and processed, while on the DO$ side they are not. For example corrtype is set to "ada" on sun unix side, while on the DOS side corrtype is not set or defined. Any help appreciated.
