From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)

Description of problem:
conflicting types for `wchar_t' in /usr/X11R6/include/X11/Xlib.h 
and /usr/lib/gcc-lib/i386-redhat-linux/3.2/include/stddef.h

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. I can not simplify the program , since my program eniroment are very 
complicated But I list my sample :
    when building my library, produce following error :

--- Building NdmFm LIB ---
ATALOG -Dlinux -D__i386__ -D_POSIX_C_SOURCE=199309L -D_POSIX_SOURCE -
E=500L -D_BSD_SOURCE -D_SVID_SOURCE  -I/nice/nice.v2/LINUX_V8/inc -
11 -I/usr/X11R6/include -L/nice/nice.v2/LINUX_V8/lib -L/usr/X11R6/lib -
11 -lXm -lXp -lXt -lSM -lICE -lXext -lX11 -lXt -lX11 -c UxXt.c

Actual Results:  In file included from /usr/X11R6/include/X11/Intrinsic.h:56,
                 from UxXt.c:25:
/usr/X11R6/include/X11/Xlib.h:78: conflicting types for `wchar_t'
/usr/lib/gcc-lib/i386-redhat-linux/3.2/include/stddef.h:294: previous 
of `wchar_t'

Comment 1 Jakub Jelinek 2003-03-19 20:13:40 UTC
This is an XFree86 thing.

Comment 2 Mike A. Harris 2003-03-20 01:37:18 UTC
#ifndef X_WCHAR
#include <stddef.h>
#ifdef __UNIXOS2__
#include <stdlib.h>
/* replace this with #include or typedef appropriate for your system */
typedef unsigned long wchar_t;

Comment 4 Ulrich Drepper 2003-03-20 03:28:04 UTC
Looking at the part of the header you posted, W_WCHAR shouldn't be defined. 
Then wchar_t is picked up from stddef.h.  Of course I don't know what other
effects this will have.  But I would guess nothing which conflicts or which
would disable functionality.

Comment 6 Mike A. Harris 2004-09-28 23:01:45 UTC
