# We have a 4 pass build process:
#
# Pass 1. export - Create generated headers and stubs. Publish public headers to
#		dist/<arch>/include.
#
# Pass 2. libs - Create libraries. Publish libraries to dist/<arch>/lib.
#
# Pass 3. all - Create programs. 
#
# Pass 4. install - Publish programs to dist/<arch>/bin.
#
# Parameters to this makefile (set these before including):
#
# a)
#	TARGETS	-- the target to create 
#			(defaults to $LIBRARY $PROGRAM)
# b)
#	DIRS	-- subdirectories for make to recurse on
#			(the 'all' rule builds $TARGETS $DIRS)
# c)
#	CSRCS   -- .c files to compile
#			(used to define $OBJS)
# d)
#	PROGRAM	-- the target program name to create from $OBJS
#			($OBJDIR automatically prepended to it)
# e)
#	LIBRARY	-- the target library name to create from $OBJS
#			($OBJDIR automatically prepended to it)

# HACK ALERT
#
# The only purpose of this rule is to pass Mozilla's Tinderbox depend
# builds (http://tinderbox.mozilla.org/showbuilds.cgi).  Mozilla's
# Tinderbox builds NSPR continuously as part of the Mozilla client.
# Because NSPR's make depend is not implemented, whenever we change
# an NSPR header file, the depend build does not recompile the NSPR
# files that depend on the header.
#
# This rule makes all the objects depend on a dummy header file.
# Touch this dummy header file to force the depend build to recompile
# everything.
#
# This rule should be removed when make depend is implemented.
#

DUMMY_DEPEND_H = $(topsrcdir)/config/prdepend.h

$(filter $(OBJDIR)/%.$(OBJ_SUFFIX),$(OBJS)): $(OBJDIR)/%.$(OBJ_SUFFIX): $(DUMMY_DEPEND_H)
