I compiled omniORB 2.7.1 on a FreeBSD 3.2 (RELEASE) system using
the pthreads from libc , gnu make and egcs 1.1.2.

* the config file for FreeBSD builds :

- omniORB 2.7.1 shared and static libraries
- omniORB utils linked static against the omniORB libs
    [ not enabled by default, edit x86_freebsd_3.2.mk to do so. - SLL ]

* to build applications with omniORB on FreeBSD use
	CXXFLAGS = -D_REENTRANT -D_THREAD_SAFE
	CXXFLAGS += -D__x86__ -D__freebsd__ -D__OSVERSION__=3
	CXXFLAGS += -I<YOUR_OMNIORB_INSTALL_DIRECTORY>/include

	dynamic linked binaries:
	LDFLAGS = -L<YOUR_OMNIORB_DIRECTORY>/lib/x86_freebsd_3.2
	LDFLAGS	+= -lomniORB2 -lomniDynamic2 -ltcpwrapGK -lomnithread
	LDFLAGS += -Wl,-rpath,<YOUR_OMNIORB_DIRECTORY>/lib/x86_freebsd_3.2

	static linked binaries:
	LDFLAGS = -L<YOUR_OMNIORB_INSTALL_DIRECTORY>/lib/x86_freebsd_3.2
	LDFLAGS	+= -Wl,-Bstatic 
	LDFLAGS	+= -lomniORB2 -lomniDynamic2 -ltcpwrapGK -lomnithread
	LDFLAGS	+= -Wl,-Bdynamic

	!!! link with the -lpthread flag !!!

During the port i run into the following problems:

* fcntl.h doesn't define O_SYNC, so i used O_FSYNC instead
	omniORB-2.7.1/src/appl/omniNames/log.cc
	omniORB-2.7.1/src/appl/omniNames/omniNames.cc

* need to include unistd.h and sys/wait.h on freebsd in
	omniORB-2.7.1/src/tool/omniidl2/driver/drv_fork.cc
	omniORB-2.7.1/src/tool/omniidl2/driver/drv_preproc.cc


* stock egcs 1.1.2 doesn't support the FreeBSD specific -pthread linking flag
	als the supplied gcc (2.7.2) does.
	just using -lc_r results into binaries linked against libc_r and libc.
	'cause libc_r comes first it may work but isn't a good idea IMHO.

	so i modified the egcs-1.1.2/gcc/config/i386/freebsd-elf.h file 
	the diff is attached below. 
	apply it and rebuild egcs.	
	[i rename the compiler drivers from gcc and g++ to egcs and egcs++
	just to make sure i don't use the supplied system gcc/g++]
