Glade Probs with new FC8 Installation

[OctalPLug]

With a newly installed FC8 I have encountered problems compiling a Glade project
whose compilation went pretty smoothly under FC6. Perhaps someone here can
help or at least direct me to a more appropriate group for posting this problem.

After autogen.sh, and so on when I execute make 2>errs the errs file shows a number
of entries, the first few of which are as follows:

In file included from /usr/include/libgnome-2.0/libgnome/gnome-util.h:31,
from /usr/include/libgnome-2.0/libgnome/libgnome.h:48,
from ./gnome.h:6,
from support.h:10,
from aux1.c:8:
/usr/include/stdlib.h:691: error: expected identifier or ‘(’ before ‘int’
/usr/include/stdlib.h:691: error: expected ‘)’ before ‘>=’ token
In file included from /usr/include/libbonoboui-2.0/bonobo/bonobo-dock.h:56,
from /usr/include/libgnomeui-2.0/libgnomeui/gnome-app.h:49,
from /usr/include/libgnomeui-2.0/libgnomeui/libgnomeui.h:35,
from ./gnome.h:14,
from support.h:10,
from aux1.c:8:
/usr/include/libbonoboui-2.0/bonobo/bonobo-dock-band.h:107: error: expected ‘;’,
‘,’ or ‘)’ before ‘&’ token
/usr/include/libbonoboui-2.0/bonobo/bonobo-dock-band.h:109: error: expected ‘;’,
‘,’ or ‘)’ before ‘&’ token
-----------------

Focusing on the first offending line,namely,

/usr/include/stdlib.h:691: error: expected identifier or ‘(’ before ‘int’

I look at the FC8 /usr/include/stdlib.h file and see that line 691 reads:
extern int abs(int __x) __THROW __attribute__ ((__const__)) __wur;

In the FC6 /usr/include/stdlib.h the line is in a different place (line 785) but looks
identical:
extern int abs (int __x) __THROW __attribute__ ((__const__)) __wur;

-------------------

I am not exactly a newbie, but I am no guru either. Any suggestions as
to how I can get past those kinds of errors would be greatly appreciated.
