Hi Eljay,
Thanks for the reply. I thought so too...that's where I discovered the
example etc.
I am using the GNU C library (I think)...When I do a ldd on an executable
thus created I see the following:

        ....
        librt.so.1 =>    /usr/lib/librt.so.1
        libm.so.2 =>     /usr/lib/libm.so.2
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libz.so.1 =>     /usr/lib/libz.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libpthread.so.1 =>       /usr/lib/libpthread.so.1
        libc.so.1 =>     /usr/lib/libc.so.1        libaio.so.1 =>  
/usr/lib/libaio.so.1
        libmd5.so.1 =>   /usr/lib/libmd5.so.1
        libgcc_s.so.1 =>         /usr/sfw/lib/libgcc_s.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2
        libscf.so.1 =>   /usr/lib/libscf.so.1
        libdoor.so.1 =>  /usr/lib/libdoor.so.1
        libuutil.so.1 =>         /usr/lib/libuutil.so.1
        /platform/SUNW,Sun-Blade-2500/lib/libc_psr.so.1
        /platform/SUNW,Sun-Blade-2500/lib/libmd5_psr.so.1

As libgcc_s.so.1 is in the path I would assume it is.  But the compiler
can't find the execinfo.h file either that describes the prototype for these
functions let alone the functions themselves. Please help...

Alex
