Well actually, it's not the compiler/linker that initialised .bss -
it's the dynamic loader. In the case of U-Boot, it's the Flash->RAM
relocation code.

I don't know of anyone that has even tried, let alone succeeded in
compiling U-Boot with a Microsoft compiler. I've heard of cygwin
attempts (that from memory have also failed miserably)

Generally speaking, gnu based tools are your best bet. Speaking of
which, we really should have a list of 'supported tools' which are
known to successfully build U-Boot...
