# can't do that. Similarly, if you compile uClibc vs Linux 2.4.x kernel headers,
# but then run on Linux 2.0.x, lchown will be compiled into uClibc, but won't

# "malloc" on the other hand is a bit bigger, but is pretty smart thereby
# minimizing memory wastage and reusing already allocated memory. This
# can be lots faster and safer IMHO.
#
# "malloc-930716" is from libc-5.3.12 and was/is the standard gnu malloc.
