Something I didn't take into account with this is that the configure
mechanism bypasses the headers in most cases, and checks directly by
using the linker.

looks like using the DATA keyword in cygwin.din wasn't such a good idea

_ctype_ DATA
_sys_errlist DATA
_sys_nerr DATA

configure can't find sys_errlist or sys_nerr, in .../src/libiberty.

Either the test in .../src/libiberty/configure needs to be changed to
the same as the one in .../src/bash/configure (which would also fix
mingw32) or the DATA keyword needs to be removed from these 2 in
