[CentOS] CentOS 4.2 x86_64 address errors.

[Michael Ubell]

Compiling the library and program with -m32
makes the problems go away, but gdb will
not work properly against such a program.
It cannot read the registers at a failure or breakpoint.

Is there some way to configure gdb to work
in this environment?  I have tried recompiling
gdb -m32 but I can't get that to compile.

Any idea wehre asm-i386/prctl.h might be?
