# Specify this if you want to hard-code the operating system to appear
# in the lower-left hand corner of -mdoc manuals.
#
# CFLAGS	+= -DOSNAME="\"OpenBSD 5.5\""

# IFF your system supports multi-byte functions (setlocale(), wcwidth(),
# putwchar()) AND has __STDC_ISO_10646__ (that is, wchar_t is simply a
# UCS-4 value) should you define USE_WCHAR.  If you define it and your
# system DOESN'T support this, -Tlocale will produce garbage.
# If you don't define it, -Tlocale is a synonym for -Tacsii.
#
CFLAGS	 	+= -DUSE_WCHAR

# If your system has manpath(1), uncomment this.  This is most any
# system that's not OpenBSD or NetBSD.  If uncommented, manpage(1) and
# makewhatis(8) will use manpath(1) to get the MANPATH variable.
#CFLAGS		+= -DUSE_MANPATH

# If your system does not support static binaries, comment this,
# for example on Mac OS X.
STATIC		 = -static
# Linux requires -pthread to statically link with libdb.
