I switched entropy to gcc-3.1pre as the main compiler, recompiled 
glibc-2.2.5cvs, installed it and sendmail would no longer start:

[root@entropy:~]# /usr/sbin/sendmail.sendmail
/usr/sbin/sendmail.sendmail: relocation error: /usr/sbin/sendmail.sendmail: 
undefined symbol: __umoddi3
[root@entropy:~]# nm /usr/sbin/sendmail.sendmail|grep divdi3
10087b5c T __divdi3
         U __udivdi3
[root@entropy:~]# readelf -a /usr/sbin/sendmail.sendmail|grep divdi3
100b7498  00006c15 R_PPC_JMP_SLOT        100b7498  __udivdi3                 + 
0
   108: 100b7498  1016 FUNC    GLOBAL DEFAULT  UND __udivdi3
   970: 10087b5c  1176 FUNC    GLOBAL DEFAULT   11 __divdi3
  1330: 100b7498  1016 FUNC    GLOBAL DEFAULT  UND __udivdi3

sendmail was recently recompiled with uptodate binutils/gcc-2.95.4 against a 
post 28 Feb glibc-2.2.5cvs.

Anything else you need to know?
