bug#14644: emacsclient.c fails to compile

[Paul Eggert]

Perhaps "make clean; ./configure; make" will fix whatever
state your build is wedge in....

Anyway, I'm surprised that lib/getopt.h is built on your platform,
as the stock getopt.h should be OK.
Could you please send the part of
config.log that talks about getopt?
Mine says the following (Fedora 17):
