Nope.  The compiler doesn't care for its include files. ;-)

So what's the problem?  Simply declare the storage to belong to the
.bss section inside the assembler code, and the linker will take care
to arrange for it, together with the other compiler-generated .bss
variables.  The startup code will clear that SRAM area to 0.

Alternatively, put it into .data, then you can initialize it to
arbitrary values, but it'll also consume flash (to write down the
initialization values).
