FC3 on ix86, gcc, library and backward compatibility

[Jean-Claude MARQUES]

Hello

For numerical calculus, I used a library with a RH 7.3. I upgraded the 
distribution with a FC 3. Since this date, I have the following problem :

/usr/local/vni/CTT3.0/lib/lib.linux/libimslcmath.so: undefined reference 
to `__ctype_b'

and the same with other __ctypes_*.  "*" means toupper , tolower or b

I searched ont the net but didn't got anything for help.

In ctype.h and libc, can be found __ctype_*_loc.
I found __ctype_* in xlocale.h, but I don't know how to use it.

Configuration :
**gcc --version : gcc (GCC) 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)
**uname -r : 2.6.9-1.667smp
**uname -p : i686
**ll /lib/libc.so.6 : lrwxrwxrwx    1 root     root           13 nov 24  
2003 /lib/libc.so.6 -> libc-2.3.2.so

if anybody can help me, it would be nice.

Best regards.
