INTEGRATION: CWS dmake411 (1.7.4); FILE MERGED

2007/09/14 00:08:59 vq 1.7.4.3: #i81296# Remove bit recycling for F_VISITED/F_USED. Use only F_VISITED.
2007/08/18 03:16:50 vq 1.7.4.2: #i10000# Add some comments.
2007/07/24 23:00:26 vq 1.7.4.1: #i78776# New function macro $(normpath[,para] list) to normalise the
elements of list and a macro extension $(macro_name:n) to normalise
the content of macro_name. The normalization is done token-wise and
quotes are preserved.
On cygwin the result honors the setting of .WINPATH to determine the
output format.  If the optional parameter para is given in the
$(normpath ...) case its expanded value is used to override the
.WINPATH setting for the output of the function macro.
