Oliver Bolte 736f032896 INTEGRATION: CWS dmake48 (1.9.2); FILE MERGED 
2007/03/17 19:00:37 vq 1.9.2.1: #i73499# Add new .WINPATH attribute to generate Windows style paths
(with regular slashes) instead of the default cygwin style (POSIX)
paths for dmake's dynamic macros.

This attribute is specific for cygwin dmake executables and non-cygwin
environments ignore this attribute.

The windows style paths use regular slashes ('/') instead of the
usual windows backslash ('\') as directory separator to avoid quoting
problems (It still is a cygwin dmake!) and cygwin as well as native
windows programs should have no problems using this (c:/foo/bar) path
representation.

The affected macros are $@, $*, $>, $?, $<, $&, $^ and $(PWD),
$(MAKEDIR) and $(TMD).

Examples:

Content of $(PWD) without .WINPATH (default):  /cygdrive/c/temp

Content of $(PWD) with .WINPATH set:           c:/temp

/* $RCSfile: dmake.c,v $
-- $Revision: 1.10 $
-- last change: $Author: obo $ $Date: 2007-06-12 06:04:45 $
--
-- SYNOPSIS
-- The main program.
--
-- DESCRIPTION
--
-- dmake [-#dbug_string] [ options ]
-- [ macro definitions ] [ target ... ]
--
-- This file contains the main command line parser for the
-- make utility. The valid flags recognized are as follows:
--
-- -f file - use file as the makefile
-- -C file - duplicate console output to file (MSDOS only)
-- -K file - .KEEP_STATE file
-- -#dbug_string - dump out debugging info, see below
-- -v[cdfimrtw] - verbose, print what we are doing, as we do it
-- -m[trae] - measure timing information
--
-- options: (can be catenated, ie -irn == -i -r -n)
--
-- -A - enable AUGMAKE special target mapping
-- -B - enable non-use of TABS to start recipe lines
-- -c - use non-standard comment scanning
-- -d - do not use directory cache
-- -i - ignore errors
-- -n - trace and print, do not execute commands
-- -t - touch, update dates without executing commands
-- -T - do not apply transitive closure on inference rules
-- -r - don't use internal rules
-- -s - do your work silently
-- -S - force Sequential make, overrides -P
-- -q - check if target is up to date. Does not
-- do anything. Returns 0 if up to date, -1
-- otherwise.
-- -p - print out a version of the makefile
-- -P# - set value of MAXPROCESS
-- -E - define environment strings as macros
-- -e - as -E but done after parsing makefile
-- -u - force unconditional update of target
-- -k - make all independent targets even if errors
-- -V - print out this make version number
-- -M - Microsoft make compatibility, (* disabled *)
-- -h - print out usage info
-- -x - export macro defs to environment
-- -X - ignore #! lines found in makefile
--
-- NOTE: - #ddbug_string is only availabe for versions of dmake that
-- have been compiled with -DDBUG switch on. Not the case for
-- distributed versions. Any such versions must be linked
-- together with a version of Fred Fish's debug code.
--
-- NOTE: - in order to compile the code the include file stddef.h
-- must be shipped with the bundled code.
