BuildDPS Silliness

[Harold L Hunt II]

xc/config/cygwin.cf/BuildDPS was defined to NO.  The reasoning behind 
this was that DPS was not available on Cygwin.

However, it seems that there was never a BuildDPS flag being checked by 
the rest of the build system.  This flag seems to have always been 
BuildDPSLibraries.  Thus, the BuildDPS NO had no effect.

I had just noticed that some DPS programs were failing to build while I 
was having trouble with flex.  I thought that the BuildDPS flag name had 
changed, so I changed the #define to BuildDPSLibraries NO.  I committed 
that to xoncygwin HEAD.  Then I noticed that the flag appears to have 
never been BuildDPS.  Thus, it should probably just be removed 
completely, since it wasn't working in the first place.  I am rebuilding 
the tree now and will probably go ahead and remove the 
BuildDPS/BuildDPSLibraries flag(s) if there are no errors during the build.

Does this seem reasonable to all, or have I missed something?
