# We used to have a 4 pass build process.  Now we do everything in one pass.

# export - Create generated headers and stubs. Publish public headers to

#          dist/<arch>/include.

#          Create libraries. Publish libraries to dist/<arch>/lib.

#          Create programs.

# libs - obsolete.  Now a synonym of "export".

# all - the default makefile target.  Now a synonym of "export".

# install - Install headers, libraries, and programs on the system.

# 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.
