Hi Tux, I think I found the problem. I snipped the cppsym c code from the Configure script and recompiled it and got a few symbols out of 792 possibilities. Few of the *64* Symbols are available and I think this is the problem. I'm not sure if an option was missed when the package was installed. If not, I Here's the list:

$ ./cppsym
_AIX
_AIX32
_AIX41
_AIX43
_ALL_SOURCE
_ANSI_C_SOURCE
_BIG_ENDIAN
__BIG_ENDIAN__
_IBMR2
_LARGE_FILE_API
_LONG_LONG
_LP64
__LP64__
_POSIX_C_SOURCE
_POSIX_SOURCE
_POWER
_XOPEN_SOURCE
_XOPEN_SOURCE_EXTENDED
__unix
__unix__
[download]

Any light you can shed on this would be greatly appreciated!
