Subject: INTEGRATION: CWS dmake411 (1.4.2); FILE MERGED 2007/09/23 22:05:02 vq
 1.4.2.2: #i81855# More changes for the OS/2 port. Patch provided by Yuri
 Dario. 2007/07/24 23:00:27 vq 1.4.2.1: #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.
