PROBLEM:
	Hex/Octal decoding with sscanf from kernel library does not work
	within kernel 2.4.20

DESCRIPTION:
	Line 570 in lib/vsprintf.c

			14677 11. Okt 2001  vsprintf.c

	holds '	base = 10; '

	which prevents the real conversion routines ('simple_strtoul' a.s.o.)
	from decoding numbers from bases other than 10.

(possible?) SOLUTION:

	Changing line 570 from ' base = 10; ' to ' base = 0;' works for me.
	I have found no side effects up to now, but I am not sure that there
	might be some.

I am by no means a kernel professional or an experienced c-programmer, so I
hope that some of the linux gurus can have a look at this little problem.

I am sorry not to have any sample code for you, that shows the error.
I have discovered the problem on writing a small kernel module for driving
a home brewed TUSB3410-development-board, and this modul needs the special
hardware to be functional.

If there should be some interest on this kernel module for USB hard- and
software development (the TUSB3410 from Texas Instruments is a programmable
USB to serial converter), I would be proud to release this small work to the
public (including the hardware and, if of further interest, the TUSB-code).

Thanks for all the good linux code I can work with, and

Best regards
