# @(#) Makefile 1.6 93/06/18 22:29:40
## BEGIN CONFIGURATION STUFF
# In the unlikely case that your compiler has no hooks for alternate
# compiler passes, use a "cc cflags -E file.c | unproto >file.i"
# pipeline, then "cc cflags -c file.i" to compile the resulting
# intermediate file.
#
# Otherwise, the "/lib/cpp | unproto" pipeline can be packaged as an
# executable shell script (see the provided "cpp.sh" script) that should
# be installed as "/whatever/cpp". This script should then be specified
# to the C compiler as a non-default preprocessor.
#
PROG = unproto
PIPE =
# The overhead and problems of shell script interpretation can be
# eliminated by having the unprototyper program itself open the pipe to
# the preprocessor. In that case, define the PIPE_THROUGH_CPP macro as
# the path name of the default C preprocessor (usually "/lib/cpp"),
# install the unprototyper as "/whatever/cpp" and specify that to the C
# compiler as a non-default preprocessor.
#
# PROG = cpp
# PIPE = -DPIPE_THROUGH_CPP=\"/lib/cpp\"
# Some compilers complain about some #directives. The following is only a
# partial solution, because the directives are still seen by /lib/cpp.
# Be careful with filtering out #pragma, because some pre-ANSI compilers
# (SunOS) rely on its use.
#
# SKIP = -DIGNORE_DIRECTIVES=\"pragma\",\"foo\",\"bar\"
#
SKIP =
# The bell character code depends on the character set. With ASCII, it is
# 7. Specify a string constant with exactly three octal digits. If you
# change this definition, you will have to update the example.out file.
#
# BELL = -DBELL=\"007\"
# Some C compilers have problems with "void". The nature of the problems
# depends on the age of the compiler.
#
# If your compiler does not understand "void" at all, compile with
# -DMAP_VOID. The unprototyper will replace "void *" by "char *", a
# (void) argument list by an empty one, and will replace all other
# instances of "void" by "int".
#
# If your compiler has problems with "void *" only, compile with
# -DMAP_VOID_STAR. The unprototyper will replace "void *" by "char *",
# and will replace a (void) argument list by an empty one. All other
# instances of "void" will be left alone.
#
# If neither of these are defined, (void) argument lists will be replaced
# by empty ones.
#
# MAP = -DMAP_VOID_STAR
# Now that we have brought up the subject of antique C compilers, here's
# a couple of aliases that may be useful, too.
#
# ALIAS = -Dstrchr=index
# If you need support for functions that implement ANSI-style variable
# length argument lists, edit the stdarg.h file provided with this
# package so that it contains the proper definitions for your machine.
