Zsh 4.2.3 and 4.2.4 are built improperly on AMD64 Gentoo Linux,
profile 2005.0.  Here's what the configure script shows:

checking where the RLIMIT macros are located... configure: WARNING: RLIMIT MACROS NOT FOUND:  please report to developers
/dev/null
checking if rlim_t is longer than a long... no
checking if the rlim_t is unsigned... yes
checking for rlim_t... yes
checking for limit RLIMIT_AIO_MEM... no
checking for limit RLIMIT_AIO_OPS... no
checking for limit RLIMIT_AS... yes
checking for limit RLIMIT_LOCKS... yes
checking for limit RLIMIT_MEMLOCK... yes
checking for limit RLIMIT_NPROC... yes
checking for limit RLIMIT_NOFILE... yes
checking for limit RLIMIT_PTHREAD... no
checking for limit RLIMIT_RSS... yes
checking for limit RLIMIT_SBSIZE... no
checking for limit RLIMIT_TCACHE... no
checking for limit RLIMIT_VMEM... no
checking for limit RLIMIT_SIGPENDING... yes
checking for limit RLIMIT_MSGQUEUE... yes
checking if RLIMIT_VMEM and RLIMIT_RSS are the same... no
checking if RLIMIT_VMEM and RLIMIT_AS are the same... no


My little workaround is to apply the following patch and run
autoconf.  This doesn't really fix the problem, it just gets zsh built
for me.
