[ale] Remedial C++/gcc/build question

[John Mills]

Jim -

Thanks for the lead. I may have tracked this back to 
'/opt/gnome/include/glib-2.0/glib/gmacros.h':

#if     __GNUC__ >= 4
#define G_GNUC_SENTINEL(x) __attribute__((__sentinel__(x)))
#else
#define G_GNUC_SENTINEL(x)
#endif

I'm building with gcc-3.3.5, so the macro "G_GNUC_SENTINEL(x)" has an 
empty definition as suggested by the compilation error message:

gcc -fno-strict-aliasing -g -O2 -Wall -I../include -I/usr/X11R6/include 
-pthread -DXTHREADS -D_REENTRANT -DXUSE_MTSAFE_API

Any suggested work-arounds?
