[Bug-gnulib] Getopt fix installed

[Simon Josefsson]

On powerpc-apple-darwin5.5 I get:

/usr/bin/ld: warning unused multiple definitions of symbol _opterr
../gl/.libs/libgnu.a(getopt.o) definition of _opterr in section (__DATA,__data)
/usr/lib/libSystem.dylib(getopt.o) unused definition of _opterr

It seems that the mapping of opterr was forgotten.

Or was that intentional somehow?

I have installed the patch below.

Btw, for every file that include config.h, I get warnings:

checking whether optreset is declared... no
...
internal.h:58: warning: could not use precompiled header 
'/usr/include/unistd.p', because:
internal.h:58: warning: macro 'optarg' defined by ../config.h conflicts with 
precomp

        * getopt.m4: Replace opterr.
