2.6.14-rc5-mm1: reiser4: ICE with gcc 2.95

[Adrian Bunk <bunk@stusta.de>]

Trying to compile 2.6.14-rc5-mm1 with gcc 2.95 and 
CONFIG_REISER4_DEBUG=y results in the following ICE:

Although this is technically an error in gcc 2.95, the code should be 
fixed to work around this issue since gcc 2.95 is a supported compiler 
for compiling kernel 2.6.
