Hi Peter,

I think this change has to be reverted; it breaks compilation of gsftopk:

../../../texk/gsftopk/gsftopk.c:418:8: error: redefinition of 'struct 
option'
/home/kbrown/src/texlive/Build/test/texk/kpathsea/getopt.h:99:8: note: 
originally defined here
Makefile:377: recipe for target `gsftopk.o' failed

Regards,

Ken
