GCC3.0 support: Kernel 2.4.5 compilation troubles

Hello all!
trying to compile kernel I got following:

make bzImage

Best regards,

Use 2.95 or 2.96 not gcc 3.0 if you want a peaceful time of it. If you are feeling bold and adventurous then

1. Get 2.4.6pre5 - this has the compile bug you see fixed (older gcc
just missed seeing/reporting it)

2. Look back in the kernel archives and you'll find some patches for
the warnings about multi-line string literals in asm blocks

Are there any plans to standarise asm inline code, for example in Documentation/CodingStyle (of course, in good friendship with gcc-3.0).
