	You do not specify which release of GCC you are using, what OS
release you are using to build it, and how you configured it, but gcc-2.95
does not exhibit this problem, so you presumably are using a backlevel
release of GCC.  The backlevel release of GCC also does not support 64-bit
applications, but gcc-2.95.1 fully supports compiling and linking 64-bit
AIX applications (use the -maix64 command-line option for both compiling
and linking).  Also, gcc-2.95 must be built on an AIX 4.3 system to
include 64-bit support -- you cannot build it on AIX 4.1 or AIX 4.2 and
access 64-bit support.

	Note that the "long long" error and "long long" support is not
releated to 64-bit support.

	I am using 64-bit support on AIX 4.3.2 S70 and 43P/260 systems
successfully.
