[avr-libc-dev] Addition of a vprintf macro in stdio.h ..? or rather a function ..?

[Björn Haase]

Hi,

when working on getting the gcc testsuite adapted for avr, I have stepped over 
the following avr-libc relevant issue: The gcc testsuite requires the target 
libc to provide a vprintf function. Avr-libc presently supplies only 
vfprintf. When additionally defining the macro

#define vprintf(A,B) vfprintf(stdout,A,B)

in stdio.h, I get the testcases working. Otherwise it would be possible to 
define a plain vprintf function instead. This however would require more code 
and more effort for a rather cosmetical fix only for testsuite purposes.
 
I think that it is not extremely urgent to clean-up this point, but I think 
that it would be helpful if the next time someone is changing something in 
stdio.h, the above addition could be incorporated (I'm not having a cvs 
checked-out avr-libc at this machine, so I can't easily prepare a proper 
patch).

Yours,

Björn
