Sorry for the broken references - I read l-k through Kernel Traffic.

Please note that 2.91.66 WILL NOT correctly build any bit of 2.4 (or
probably 2.2) on i386 that uses the kernel version of strstr, because of a
register allocation bug. This currently affects the DEPCA driver, but very
few other things.

2.95.2 is OK in this instance and elsewhere for me (YMMV).

Whether this means we should change the recommended compiler version, or
get rid of the use of (or change) the in-kernel strstr is a subject left
open for debate.
