templates, wchar_t and libstdc++

[Matthew J Fletcher]

Hi,

I have recently upgraded from a 2.95 based toolchain to a 3.4.3 one for a
application that uses lots of templates on linux and an embedded target.

I noticed that we now need to link against libstdc++ when using templates
(basic_string) in this case, otherwise the allocator_xx stuff is undefined.
I take it this is an 3.4.x optimisation, having some parts of the stl
pre-compiled, so to speak in libstdc++.

Unfortunatly, i use -fshort-wchar to use a 2byte version of basic_string,
and this is now not possible because, the basic_string constructor is within
libstdc++, which on linux means that wchar_t is 4bytes.

is there a flag (or configure option) to disable the use of the pre-compiled
libstdc++ bits of the stl, and use templates in the old fashioned (just
include files) way ?

it should be noticed that this seems to be (linux) target dependant as a
i386-unknown-elf and arm-unknown-elf toolchain work fine.

regards
