On a clean checkout or after make maintainer-clean `getopt.h' needs to 
be regenerated. In order for this to work with nmake I needed to make 
the following change:

This is not meant as a permanent fix, but just an example of what is 
necessary to make it work with nmake.

Should we define an ESCAPE_SPECIAL_CHAR variable in 
nmake.defs/gmake.defs to handle this or is there a way to make the 
platform specific decision in the makefile.w32-in without too much 
duplication?
