wait.h warnings from gpmevent.c

Anybody know what this warning is about? glibc on Linux bug, I presume? ------------------------------------------------------------------------ gcc -c -g -O3 -Wall -Wno-switch -Wpointer-arith -Winline -Wmissing-prototypes -W shadow -Demacs -I. -DHAVE_CONFIG_H -I/usr/X11R6/include /coda/Projects/XEmacs/G TK-XEmacs/src/gpmevent.c In file included from /usr/include/linux/keyboard.h:4, from /coda/Projects/XEmacs/GTK-XEmacs/src/gpmevent.c:48: /usr/include/linux/wait.h:4: warning: `WNOHANG' redefined /usr/include/bits/waitflags.h:26: warning: this is the location of the previous definition /usr/include/linux/wait.h:5: warning: `WUNTRACED' redefined /usr/include/bits/waitflags.h:27: warning: this is the location of the previous definition ------------------------------------------------------------------------ This is the same config I've been using for months. The only thing that's new is gcc and glibc, which probably got updated within the last two weeks. glibc 2.2.1 from Debian unstable, with Debian's "standard Linux headers" from libc6-dev (it's not 2.4.still-broken or anything like that). ii libc6 2.2.1-1 GNU C Library: Shared libraries and Timezone ii libc6-dev 2.2.1-1 GNU C Library: Development Libraries and Hea ii gcc 2.95.3-4 The GNU C compiler. Yes, that is a GTK build (albeit --with-gtk=no) but I have duplicated it in the current CVS release-21-2 source tree. Debian GNU/Linux "unstable", Linux kernel 2.2.18 local build. -- University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Institute of Policy and Planning Sciences Tel/fax: +81 (298) 53-5091 _________________ _________________ _________________ _________________ What are those straight lines for?
