libX11 question

[Asher Wolfstein]

Not sure where to direct this question.

I'm a relatively advanced newbie trying to compile X11... a good  
exercise I suppose.

I'm at the point where I'm compiling libX11 to obtain Xlib.h for Mesa  
as recommended in the modular build documentation.  (Is that the  
wrong place to get it?)

I get the following in my make:

KeyBind.c: In function 'XConvertCase':
KeyBind.c:844: error: 'XK_Ccedillaabovedot' undeclared (first use in  
this function)
KeyBind.c:844: error: (Each undeclared identifier is reported only once
KeyBind.c:844: error: for each function it appears in.)
KeyBind.c:845: error: 'XK_ccedillaabovedot' undeclared (first use in  
this function)
KeyBind.c:856: error: 'XK_lstrokebelowdot' undeclared (first use in  
this function)
KeyBind.c:856: error: 'XK_Lstrokebelowdot' undeclared (first use in  
this function)
KeyBind.c:860: error: 'XK_gtilde' undeclared (first use in this  
function)
KeyBind.c:860: error: 'XK_Gtilde' undeclared (first use in this  
function)
make[3]: *** [KeyBind.lo] Error 1
make[3]: Leaving directory `/home/furdash/libX11-6.2.1/src'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/home/furdash/libX11-6.2.1/src'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/furdash/libX11-6.2.1/src'
make: *** [all-recursive] Error 1

Any idea where these are defined?  I can't seem to find them anywhere.

Pointing me towards the right direction or information would be great,
Thanks!
