#Compile flags:
#ASM_SETJMP:		setjmp/longjmp reimplemented (with thread-specific
#			signal mask) in assembly. If this flag is not set,
#			the regular C library routines will be used. This
#			increases the portability but violates Pthreads
#			since the thread-specific signal mask may or may not
#			be saved. Thus, it should only be omitted when
#			absolutely necessary (for quick & dirty portability).
#C_INTERFACE:		for C-language interface; if this option is omitted,
#			a language-independent interface will be generated
#			which has been tested for Verdix/SunAda. It seems that
#			this flag should only be omitted for Verdix/SunAda.
#			All other compilers follow C interface specs.
#C_CONTEXT_SWITCH:	for context switch written in C. Notice that the
#			assembly version for the SPARC is faster but by far
#			less portable (see portability notes in pthread_disp.c
#			and assembly file *.S).
#			Internal signal handling (pthread_kill) is also much
#			slower with the context switch in C, about a factor 2.
#			speed(C context switch) =~ 1.2*speed(as context switch)
#CLEANUP_HEAP:		allocate cleanup handlers on heap (default: stack).
#DEBUG:			dump out trace information (mainly for signals).
#DEF_RR:		supports round-robin time-sliced scheduling.
#			Only works properly when MALLOC is also defined.
#DRAFT5:		defines pthread_setprio() interface bypassing attributes
#IO:			I/O operations only block current thread, not process.
#			(SunOS 4.1.x kernel configuration must include
#			light-weight processes [LWP] and aynchronous I/O [AIO];
#			under Solaris 2.x, link with -laio -ldl.)
#MALLOC:		thread-safe malloc, in conjuction with Gnu malloc lib.
#			See README for more information.
#NOERR_CHECK:		fast mutex operations without error checking.
#NO_INLINE:		no inlines for macros (internally CLEAR_KERNEL_FLAG).
#MUT_SWITCH:		forces context switch upon successful mutex_lock()
#			with regard to priorities (do not define NOERR_CHECK)
#RAND_SWITCH:		forces context switch on kernel exit at random intervals
#			and to random threads without regard to priorities
#			(do not define NOERR_CHECK)
#RR_SWITCH:		forces context switch on kernel exit (round-robin queue)
#			without regard to priorities (do not define NOERR_CHECK)
#SIGNAL_STACK:		Allows user to execute handlers in case of a stack
#			overflow. STACK_CHECK has to be on for this.
#SIM_KERNEL:		simulate kernel implementation by using dummy UNIX
#			system call in selected routines.
#SOLARIS:		support for Solaris 2.x. Need to define SVR4 as well.
#			If you want to compile for Solaris, change this
#			Makefile by deleting/inserting
#			comments wherever the string "Solaris" occurs.
#SRP:			support of mutex ceiling under stack resource
#			policy (SRP)
#			if not defined, _POSIX_THREADS_PRIO_PROTECT has to be
#			undefined in unistd.h!
#STACK_CHECK:		lock page to cause bus error / illegal instruction
#			on stack overflow
#STAND_ALONE:		micro-kernel for VME SPARC Engine 1E; works only in
#			conjunction with SRP and no other compile options
#SVR4:			System V Release 4 UNIX system. For portability.
#			Currently supports Solaris only. If not defined,
#			BSD (Berkley) UNIX is assumed (currently SunOS 4.1.x).
#TIMER_DEBUG:		dump out trace information for SIGALRM signals and timer
