[patch] RFA Fixes for ICC compilation errors

[Jules Bergmann]

This patch works around three compilation errors with ICC 9.0.  One is 
an overloaded function that ICC finds ambiguous, the other two seem to 
be caused by function return types that use member class templates.

I tested these with ICC-9.0 (32-bit), gcc-3.4 and gcc-4.0.

Stefan, is this Ok to apply?
