Hi Steve,
I am not sure if it shouldn't be initialized at start-up (obviously it should
not but...)
This is from gcc-internals:
`ASM_OUTPUT_SKIP (STREAM, NBYTES)'
A C statement to output to the stdio stream STREAM an assembler
instruction to advance the location counter by NBYTES bytes.
***Those bytes should be zero when loaded.*** NBYTES will be a C
expression of type `int'.
I do not know why they should be zeros (just leave them uninitialized...), but
that's all I know about it.
If people can live with uninitialized data, I'll remove zeros from there.
