Patch from Ralf Corsepius <>:
After upgrading my linux box to the brand new SuSE 6.2 release, which is glibc-2.1 based, I came across a bug in RTEMS - IIRC, I even warned you about it about 1/2 a year ago, but nothing has been done since then :-. The *.m4 macros to check for SYSV/IPC are broken for linux/glibc2.1, because they assume that linux always defines union semun, which isn't true anymore for glibc2.1 (the manpage for semctl states _X_OPEN specifies it this way). Therefore I have tried to implement a more general approach for handling SYSV for unix/posix which checks for presence of struct semun, instead of trying to evaluate OS specific preprocessor symbols. This approach is a bit adventureous, because I only tested it with linux/glibc2.1 and linux/libc5, but not under other Unix variants RTEMS supports. I am quite confident it will work on other hosts, too, but who knows :-. [FYI: I think this might also is the cause of some problems with RedHat 6.X / Mandrake linux recently reported on the rtems list -- rtems-4.0.0 can not be build for posix on any glibc2.1 based host] Furthermore the patch below contains a couple of minor fixes and configuration cleanups, which IMO should be applied before releasing a new snapshot. To apply this patch: cd <source-tree> patch -p1 < rtems-rc-19990709-8.diff ./autogen
