Conflicting getopt definition

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

converters/recode doesn't build on Mac OS X because it brinsg it's  
own GNU getopt and teh sysbols collide with those in libc:

/usr/bin/ld: multiple definitions of symbol _getopt
/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/../../../libc.dylib 
(getopt.So) definition of _getopt
../lib/libreco.a(getopt.o) definition of _getopt in section  
(__TEXT,__text)
/usr/bin/ld: multiple definitions of symbol _opterr
/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/../../../libc.dylib 
(getopt.So) definition of _opterr
../lib/libreco.a(getopt.o) definition of _opterr in section  
(__DATA,__data)
/usr/bin/ld: multiple definitions of symbol _optind
/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/../../../libc.dylib 
(getopt.So) definition of _optind
../lib/libreco.a(getopt.o) definition of _optind in section  
(__DATA,__data)
/usr/bin/ld: multiple definitions of symbol _optopt
/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/../../../libc.dylib 
(getopt.So) definition of _optopt
../lib/libreco.a(getopt.o) definition of _optopt in section  
(__DATA,__data)
collect2: ld returned 1 exit status

Since this has probably happened with umptenth other pacakges before:  
What's the standard way to correct this?
