gcc 2.95.3 will do something like the following:

stl_check.cpp:15: no class template named `map' in `struct Foo<T>'
stl_check.cpp:16: no class template named `map' in `struct Foo<T>'
gcc 3.x (3.3pre, at least) swallows it nicely.
The problem here is the 'typename' part: without that gcc
2.95.3 compiles it fine. gcc 3, however, warns that
"implicite typenames are deprecated", and this kills my
builds (i always use -Werror :/).
