Problems Compiling checkpassword .90

Hello, Im not sure if this is documented anywhere as i cant find any 
reference to this problem on google. But I'm having some problems 
compile checkpassword on a SuSE 9.0 server.

The following is the error log i get

linux:/usr/local/src/checkpassword-0.90 # make
./load checkpassword prot.o unix.a byte.a  `cat \
shadow.lib` `cat crypt.lib` `cat s.lib`
checkpassword.o(.text+0x6e): In function `main':
: undefined reference to `errno'
checkpassword.o(.text+0xf9): In function `main':
: undefined reference to `errno'
checkpassword.o(.text+0x23e): In function `main':
: undefined reference to `errno'

unix.a(pathexec_run.o)(.text+0x167): In function `pathexec_run':

collect2: ld returned 1 exit status
make: *** [checkpassword] Error 1
linux:/usr/local/src/checkpassword-0.90 #

If it helps at all i'm running gcc-3.3.1-29. Any help concerning this 
issue would be very apprecieated.
