mkaply has brought this up a number of times and timeless & I just went over it
again on irc.  For some reason (mkaply can fill in the details), XP_PC is used
on platforms other than MS Windows, yet every developers continue to use XP_PC
as a win32 exculsive define.

To start with, we need to add -DXP_WIN32 to config/config.mak so that it is
always defined instead of requiring xp_core.h.  That's a 30sec process.  Then we
need to scrub XP_PC from the source trees.  That should eat up a couple of
hours.  Once that's done, we should be able to remove XP_PC from
config/config.mak and listen to the develoeprs wonder why their new code breaks.

In a number of cases, XP_PC is used for both because it relates to 
"Intel" type things, or things that are consistent between OS/2 and 

Another note - I believe there should be XP_WIN and XP_WIN32. XP_WIN 
for stuff that is generic windows (like include windows.h for instance) 
and XP_WIN32 for WIN32 specific stuff and probably eventually XP_WIN64.

I'll be more than happy to help with this change next week :)

"Intel" sort of things?  Isn't that what -D_X86_ is for? So does OS/2 use any
code that falls under XP_WIN?

Add -DXP_WIN & -DXP_WIN32 to default WIN32 OS_CFLAGS

Specific examples of XP_PC between OS/2 and Windows

DLL names:


File system stuff (back slashes)


Other stuff that I don't know:


URl conversion:


Context menus:



By the way, if you search on XP_PC in lxr - every line that has the !defined 
XP_OS2 can be fixed because of this change. Very nice.

Ok, patch has been checked in.  As for the next step....mkaply, are you saying
that we should leave XP_PC or replace it with XP_WIN (or XP_DOS)?

Comment 6

I think for step one I'd like to remove a lot if the !defined XP_OS2 and elif 

I'll put together a patch in the next couple of days.

Once we get rid of the "Windows" XP_PC stuff then we can decide what to really 
call XP_PC.

Note by the way that I'll be moving stuff around in these diffs. Example:

#ifdef XP_OS2
#elif defined XP_PC
#elif defined XP_UNIX

I only had to put XP_OS2 at the beginning because of the XP_PC.

Should be:

#ifdef XP_WIN
#elif defined XP_UNIX
#elif defined XP_OS2

Shaver's been busy with other stuff lately, and isn't the best fit here

Does this bug have any relationship to bug #65727 (currently assigned to dprice)?

Comment 26

18 years ago
65727 is a side effect of this work.

When we added XP_WIN to the build, we didn't add it to component builds.

So when I started changing XPCOM to use XP_WIN, components were still using 

65727 is asking for an #ifdef somewhere in a global headers that #errors if 
XP_PC is defined without XP_WIN or XP_OS2.

This is probably a really good idea.

Note that although this bug hasn't been touched in a while, it is still being 
worked. I've just been busy.

bug cleanup - all leaf's bugzilla bugs should be assigned to leaf@mozilla.org

this should be a one time change, apologies for the spam.
