# Define these for your system as follows:
# 	-DUSG			System V
#	-DUSGr3			SVR3 (also define USG)
#	-DHPUX			HP-UX (also define USG and USGr3 appropriately)
#	-DHAVE_SYS_WAIT		USG, but have <sys/wait.h> and wait3
#	-DHAVE_SIGLIST		USG, but have sys_siglist
#	-DHAVE_DUP2		USG and not USGr3, but have dup2
#	-DHAVE_VFORK		USG, but have vfork
#	-DVFORK_MISSING		Not USG, but no vfork
#	-DNO_MINUS_C_MINUS_O	cc can't handle "cc -c foo.c -o foo.o"
#	-DPOSIX			A 1003.1 system (or trying to be)
#	-DNO_ARCHIVES		To disable `ar' archive support.
#	-DNO_FLOAT		To avoid using floating-point numbers.
#	-DENUM_BITFIELDS	If the compiler isn't GCC but groks enum foo:2.
#				Some compilers apparently accept this
#				without complaint but produce losing code,
#				so beware.
#	-DHAVE_ALLOCA_H		If you need to use <alloca.h> for alloca.
# NeXT 1.0a uses an old version of GCC, which required -D__inline=inline.

# Define these for your system as follows:
#	-DUMAX		Encore UMAX
#	-DUMAX_43	Encore UMAX 4.3 (also define UMAX)
#	-DNO_LDAV	Disable load-average checking.
# To read /dev/kmem (most Unix systems), define these if different from the
# given defaults:
#	-DKERNEL_FILE_NAME=\"/vmunix\"
#	-DLDAV_SYMBOL=\"_avenrun\"
#	-DLDAV_CVT="(double) load"
# Define:
#	-DNLIST_NAME_UNION	If `struct nlist' has a n_un member.
#	-DNLIST_NAME_ARRAY	If `n_name' is an array.
