# This is the make file for the lib subdirectory of the GIF library
# You'll need GNU gcc or some other ANSI-complient compiler.

# What devices we should be able to grab into gif images. Note that if
# you enable them the associated library must be available at link time.
# Avaiable devices:
# 1. EGA, VGA, SVGA (800x600), Hercules - all on IBM PC only.
# 2. SGI 4D Irix using gl library (Add -D__SGI_GL__).
# 3. X11 using libX.a (Add -D__X11__)
DEVS = -D__X11__

# These are the flags for gcc, in BSD4.3 or Sun O.S. 4.0.3

# If your system has all function prototypes for gcc, replace all
# the -Wxxx with -Wall. I can not add -Wimplicit as my system uses old cc
# h files.
