[Gerald Pfeifer]

On FreeBSD 4.5, dlls/ntdll/cdrom.c won't compile any longer due to the
following:

  Added mapping for errno ENOMEDIUM to STATUS_NO_MEDIA_IN_DEVICE.

  /usr/bin/gcc -c -I. -I. -I../../include -I../../include  -g -O2 -Wall -mpreferred-stack-boundary=2 -fPIC -D__WINE__ -D_NTSYSTEM_ -D_REENTRANT -I/usr/X11R6/include -o cdrom.o cdrom.c
  cdrom.c: In function `CDROM_GetStatusCode':
  cdrom.c:113: `ENOMEDIUM' undeclared (first use in this function)
  cdrom.c:113: (Each undeclared identifier is reported only once
  cdrom.c:113: for each function it appears in.)
  gmake[2]: *** [cdrom.o] Error 1
  gmake[2]: Leaving directory `/.amd_mnt/vexpert/files8/test/wine/dlls/ntdll'

The following patch fixes this in a portable way:

ChangeLog:
Gerald Pfeifer <pfeifer at dbai.tuwien.ac.at>
