# Note that the kernel source you use to compile with should be the same as the
# Linux kernel you run your apps on.  uClibc doesn't even try to achieve binary
# compatibility across kernel versions.  So don't expect, for example, uClibc
# compiled with Linux kernel 2.0.x to implement lchown properly, since 2.0.x
# 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
# work at all.  You have been warned.

# This specifies which malloc implementation is used.
# "malloc-simple" is very, very small, but is also very, very dumb 
# and does not try to make good use of memory or clean up after itself.
#
# "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.
# It is actually smaller than "malloc", but because it is based on brk/sbrk
# it will only work on systems with an MMU.
