libiberty fails to build:

make[1]: Entering directory `/cygdrive/e/gcc-src/build2/libiberty'
if [ x"" != x ]; then \
  gcc -c -DHAVE_CONFIG_H -g -O2 -I. -I../../gcc/libiberty/../include  -W -Wall -Wtraditional -pedant

 ../../gcc/libiberty/strerror.c
../../gcc/libiberty/strerror.c:465: warning: static declaration for `sys_nerr' follows non-static
../../gcc/libiberty/strerror.c:466: conflicting types for `sys_errlist'
/usr/include/sys/errno.h:23: previous declaration of `sys_errlist'
make[1]: *** [strerror.o] Error 1
make[1]: Leaving directory `/cygdrive/e/gcc-src/build2/libiberty'
make: *** [all-libiberty] Error 2
>How-To-Repeat:
1. install fresh copy of latest cygwin release
2. get gcc_3_0_1_release from CVS
3. configure --with-languages=c,c++
4. make bootstrap
>Fix:
Unknown. I know I have done this successfully in the past. Maybe something changed in Cygwin.
