From: Ben Gras Date: Mon, 29 Aug 2005 13:52:08 +0000 (+0000) Subject: Added . This file is intended to be included from X-Git-Tag: v3.1.0~255 X-Git-Url: http://zhaoyanbai.com/repos/%22https:/www.google.com/jsapi/static/roff.7.ps?a=commitdiff_plain;h=43ea6a9ce8b8a02053ce020f02bf64c703223189;p=minix.git Added . This file is intended to be included from other, user-includable config files. It only defines names that don't pollute the users namespace (start with _). still works like always; it includes sys_config.h now and defines the 'messy' names (such as CHIP) as the 'cleaner' names (such as _MINIX_CHIP). Changed some of the other include files to use sys_config.h and the 'cleaner' names. This solves some (past and future) compilation problems. --- diff --git a/include/minix/config.h b/include/minix/config.h index a6cfcbdd8..62eddf0e8 100755 --- a/include/minix/config.h +++ b/include/minix/config.h @@ -9,31 +9,35 @@ * It is divided up into two main sections.
