Description:
Compilation fails with this message (or its equivalent in other compilers).
All affected machines run Linux 2.4, the CPUs differ.

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I./../include -I./../../include -I../../include    -g -O -DDBUG_ON -DSAFE_MUTEX -g -O -DDBUG_ON -DSAFE_MUTEX   -DUNIV_LINUX -c os0proc.c
os0proc.c: In function `os_mem_alloc_large':
os0proc.c:548: `SHM_HUGETLB' undeclared (first use in this function)
os0proc.c:548: (Each undeclared identifier is reported only once
os0proc.c:548: for each function it appears in.)

How to repeat:
Try to build current 5.0.3-pre.

Hi!

This is Alexey Kopytov's code, and he has a patch pending.

I cannot assign this to Alexey K., because his name is not in the list of bugs.mysql.com.

Regards,

Heikki

The bug occurs on some old Linux distributions that have no HugeTLB support. 
Patch pushed.
