Vladimir Glazounov 88f776d969 INTEGRATION: CWS dmake47 (1.7.2); FILE MERGED 
2006/11/19 05:27:24 vq 1.7.2.11: #i71704# Let the global .SEQUENTIAL attribute implicitely set MAXPROCESS=1
and disallow MAXPROCESS to be changed if the global .SEQUENTIAL is set.
2006/11/12 05:06:38 vq 1.7.2.10: #i71422# Add a new feature: Using @@ as a recipe prefix redirects the
output (stdout and stderr) of a recipe to /dev/null (or NUL on W32)
completely suppressing the output of that recipe to the terminal.
As for the @ prefix this can be disabled using the -v[r] switch.
2006/11/09 22:33:22 vq 1.7.2.9: #i69821# Fix/improve $(TMD) handling.
2006/11/09 18:16:33 vq 1.7.2.8: #i69821# Add comment where TMD is detecting different drive letters for
native W32 dmake versions.
2006/10/08 23:27:11 vq 1.7.2.7: #i70210# Fix dmakes handling of empty dynamic prerequisites.
2006/10/08 22:57:22 vq 1.7.2.6: #i70168# Remove FIXME.
2006/10/08 22:49:03 vq 1.7.2.5: #i70168# Improve $ handling in targets/prerequisites.
2006/10/06 04:02:35 vq 1.7.2.4: #i69742# Don't targets with $ in the filepath as dynamic macros. ($$ means
a single $ in the filepath.)
2006/09/29 21:20:45 vq 1.7.2.3: #i69953# Remove NO_DRIVE_LETTERS, use HAVE_DRIVE_LETTERS instead.
2006/09/29 18:50:23 vq 1.7.2.2: #i69814# Add/fix option to make directory cache case insensitive. (Make
this the default for Windows and Mac OS X.) Added testcase.
2006/09/28 21:42:38 vq 1.7.2.1: #i69821# Fix TMD macro and add testcase.

/* $RCSfile: make.c,v $
-- $Revision: 1.8 $
-- last change: $Author: vg $ $Date: 2007-01-18 09:30:56 $
--
-- SYNOPSIS
-- Perform the update of all outdated targets.
--
-- DESCRIPTION
-- This is where we traverse the make graph looking for targets that
-- are out of date, and we try to infer how to make them if we can.
-- The usual make macros are understood, as well as some new ones:
--
-- $$ - expands to $
-- $@ - full target name
-- $* - target name with no suffix, same as $(@:db)
-- or, the value of % in % meta rule recipes
-- $? - list of out of date prerequisites
-- $< - all prerequisites associated with rules line
-- $& - all prerequisites associated with target
-- $> - library name for target (if any)
-- $^ - out of date prerequisites taken from value of $<
