INTEGRATION: CWS dmake48 (1.6.16); FILE MERGED

2007/03/17 19:00:37 vq 1.6.16.1: #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
