And a similar problem for cuserid() in posix.c:

 gcc -DHAVE_CONFIG_H -I. -I.. -I.. -I.. -I../lib -I../lib -g -O2 -Wall 
-Wmissing-prototypes -Werror -MT posix.lo -MD -MP -MF .deps/posix.Tpo -c 
posix.c  -fPIC -DPIC -o .libs/posix.o
cc1: warnings being treated as errors
posix.c: In function 'scm_cuserid':
posix.c:1705: warning: implicit declaration of function 'cuserid'
posix.c:1705: warning: assignment makes pointer from integer without a cast
make[3]: *** [posix.lo] Error 1
