Compile error in gtk+2.8.5 and gtk+2.8.6 using gcc 4.0

[Dave Chand <devchan1 bellsouth net>]

Hello,
I am trying to compile gtk+-2.8.6 and/or gtk+-2.8.5, using gcc 4.0 on  
Mac OS X, but I am getting the following compile error:

<snip>
gtkcalendar.c: In function 'gtk_calendar_init':
gtkcalendar.c:672: error: 'week_start' undeclared (first use in this  
function)
gtkcalendar.c:672: error: (Each undeclared identifier is reported  
only once
gtkcalendar.c:672: error: for each function it appears in.)
<snip>

make[1]: Leaving directory `/Users/dave/src/gtk+-2.8.6'
make: *** [all] Error 2
dave:[~/src/gtk+-2.8.6/]$

Any Ideas?
BTW GTK+-2.8.4 compiled without any errors.
