# Makefile for three SAS/C 6.51 versions of Gofer 2.30a for Amiga:
#
#   The 16 bit small version and the 32 bit regular one.
#   I haven't tried to build the 32 bit large version, but
#   the rules are in here to do it.
# 
# It will probably also work with earlier versions of SAS/C 6,
# but you may have to drop some of the optimizer options(?)

#
# IMPORTANT: make sure that you use the same compiler to build gofc
# executables (often by setting an appropriate value in the gofcc script)
# as you use to build the file runtime.o.

.SUFFIXES:	.y .c .h .o

# Choose the setup you want. Note that I use different names for the
# executables and runtime library based on the setup, because I use
# both the small and the regular version on my system.
# Remember to select the correct setup in prelude.h, i.e.,
# S_AMISAS, R_AMISAS, or L_AMISAS.

# The file amiga.c contains a custem version of the stdlib.h function
# system(). The one present in the SAS/C 6.51 library ignores the users
# choice of default shell. Thus people using (for example) WShell loose
# access to their aliases etc.
#
# The custom version is just a wrapper around the dos.library V36+
# function System() with the flag SYS_UserShell set to true. If Gofer is
# run on on a pre-V36 system, dos.library/Execute() is used instead.
#
# In addition it contains a function, amigaIsTrueConsole(), that
# is used in machdep.c to find out if we are running in a real
# shell window, in which case we can determine the width of the
# console.
#
# system() isn't used by gofc, but it only adds a few hundred bytes
# to a 200k+ executable so who cares :-)
