    Unhappy C Compile error on RHEL 5

    I am not a programmer, so please be easy on me.
    I have been asked to compile an application on RHEL 4 and 5 servers. I have been successful with a simple command as follows ;
    [tag]
    [root@rayn02 bin]# cc wholocks.c -o wholocks
    [/tag]

    However, when I try and compile on this particualter RHEL5 server it gets really messy.
    [tag]
    [root@rayn02 bin]# cc wholocks.c -o wholocks
    wholocks.c:10:1: warning: "O_RDWR" redefined
    In file included from /usr/include/fcntl.h:34,
    from wholocks.c:3:
    /usr/include/bits/fcntl.h:36:1: warning: this is the location of the previous definition
    wholocks.c: In function ‚main‚:

    /lib64/libc.so.6: could not read symbols: Bad value
    collect2: ld returned 1 exit status
    [root@rayn02 bin]#

    [/tag]

    The libc programs installed include the following;

    [tag]
    [root@rayn02 bin]# rpm -qa |grep libc
    libcap-1.10-26
    glibc-2.5-24
    glibc-headers-2.5-24
    compat-glibc-2.3.4-2.26
    glibc-common-2.5-24
    libcap-devel-1.10-26
    compat-glibc-2.3.4-2.26
    libcroco-0.6.1-2.1
    glibc-devel-2.5-24
    libcroco-0.6.1-2.1
    libchewing-0.3.0-8.el5
    glibc-2.5-24
    libcap-1.10-26
    glibc-devel-2.5-24
    libcap-devel-1.10-26
    compat-glibc-headers-2.3.4-2.26
    [/tag]

    Are they both 64-bit?
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    If you don't have a declaration of exit, you're missing a header. Specifically, you're missing <stdlib.h>.
