	GCC has known problems with templates on AIX because GCC does not
have a very advanced template generation facility and relies on WEAK
symbols to clean up after it.  AIX does not provide WEAK symbols.

	For AIX, one needs to use -fno-implicit-templates option for GCC
and explicitly instantiate the necessary templates in the code.
