# Include file and library paths

# Most Linux distributions don't separate out X11 from the rest of the
# system, but some other OSs still require extra information:

# Solaris 10:
#OPT_CPPFLAGS += -I/usr/X11/include
#LDFLAGS  += -R/usr/X11/lib -L/usr/X11/lib

# Solaris <= 9 doesn't support RANDR feature above, so disable it there
# Solaris 9 doesn't fully implement ISO C99 libc, to suppress warnings, use:
#OPT_CPPFLAGS += -D__EXTENSIONS__

# Mac OS X:
#LDFLAGS += -L/usr/X11R6/lib
