[avr-libc-dev] quell compiler warning in malloc.c

[Theodore A. Roth]

Hi,

Does this look like safe way to stop this compiler warning? (see patch
below)

  ../../../../libc/stdlib/malloc.c:197: warning: assignment makes pointer
  from integer without a cast

Joerg, I think you wrote this...

I'm also getting these, but they don't look as trivial to fix:

  ../../../libc/stdlib/qsort.c:143: warning: comparison between signed and 
unsigned
  ../../../libc/stdlib/qsort.c:143: warning: signed and unsigned type in 
conditional expression
  ../../../libc/stdlib/qsort.c:145: warning: comparison between signed and 
unsigned
  ../../../libc/stdlib/qsort.c:147: warning: comparison between signed and 
unsigned
  ../../../libc/stdlib/strtol.c:123: warning: comparison between signed and 
unsigned
  ../../../libc/stdlib/strtol.c:123: warning: comparison between signed and 
unsigned
  ../../../libc/stdlib/strtoul.c:100: warning: comparison between signed and 
unsigned
  ../../../libc/stdlib/strtoul.c:100: warning: comparison between signed and 
unsigned
