root@sheevaplug-debian:~# echo '' | flex --version
flex 2.5.35
bash: echo: write error: Broken pipe

It looks like a bug in bash on arm. It worked with zsh and it worked  
with bash an i586. :P It doesnt appear to be an alignment error! Unlike:

gcc -fPIC -g -O -I/mnta/openafs-pre1.6.0/openafs-1.6.0pre1/src/config  
-I/mnta/openafs-pre1.6.0/openafs-1.6.0pre1/include -I. -I.   
-D_LARGEFILE64_SOURCE -Wall -Wcast-align -Wstrict-prototypes  
-Wold-style-definition -Wpointer-arith -Wall -Wstrict-prototypes  
-Wold-style-definition -Werror -fdiagnostics-show-option  
-Wpointer-arith   -c cbc_encrypt.c
cc1: warnings being treated as errors

It looks like OPENAFS_GCC_SUPPORTS_MARCH is for i386/pentium only.

I don't see any ppc, alpha, mips, sparc or anything else along those  
lines in the ac files.
