Subbu,

The patch is no good.  It takes the following:

#ifdef __GNUG__
#pragma implementation "foo.h"
#endif

and turns it into:

#ifdef __GNUG__
#ifndef __CYGWIN__
#pragma implementation
#endif "foo.h"
#endif

Here is an example:

 #ifdef __GNUG__
+#ifndef __CYGWIN__
 #pragma implementation
-#pragma implementation "Map.h"
+#endif
+#ifndef __CYGWIN__
+#pragma implementation
+#endif "Map.h"
 #endif


The mistake was matching only "#pragma implementation (.*)" and 
replacing that with "#ifndef __CYGWIN__ #pragma implementation #endif 
(.*)" instead of replacing it with "#ifndef __CYGWIN__ #pragma 
implementation (.*) #endif".

Could you send in the original search and replace command (or string of 
commands) that you used to do this so that I can fix it and run the 
change again?
