Hi,
the attached patch fixes a -Wundef warning when compiling the current
svn version of libdvdread4 (as part of MPlayer) in the obvious way:
$ make
cc -MD -MP -Ilibdvdread4 -D_GNU_SOURCE -Ilibdvdcss -Wundef -Wall
-Wno-switch -Wno-parentheses -Wpointer-arith -Wredundant-decls
-Wstrict-prototypes -Wmissing-prototypes -Wdisabled-optimization
-Wno-pointer-sign -Wdeclaration-after-statement -std=gnu99
-Werror-implicit-function-declaration -O4 -march=native -mtune=native
-pipe -ffast-math -fomit-frame-pointer -fno-tree-vectorize
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE
-Ilibdvdread4 -I. -Iffmpeg -D_REENTRANT -I/usr/include/directfb
-I/usr/include/ -D_REENTRANT -I/usr/include/freetype2
-I/usr/include/dirac -I/usr/include/schroedinger-1.0
-I/usr/include/orc-0.4 -c -o libdvdread4/dvd_reader.o
libdvdread4/dvd_reader.c

Please consider applying.
Fix one warning every day. ;-)
