# Compiler warnings you want to see
WARNINGS=-Wall
# 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.

# Set it to `true' otherwise.
HAS_MMU = false

# support in libc (strtod, printf, scanf). Set it to `true' otherwise.
# If this is not true, then libm will not be built.

# Set to `true' if you want the math library to contain the full set
# of C99 math library features. Costs an extra 35k or so on x86.
DO_C99_MATH = false
# Set this to `false' if you don't have/need "(unsigned) long long int" support.

# Affects *printf and *scanf functions.
# Also omits strto(u)ll, and (u)lltostr from the library if `false'.
HAS_LONG_LONG = true
# Set this to `false' if you don't have/need locale support; `true' otherwise.
# Note: Currently only affects the ctype functions. You must also generate
# a locale file for anything but the C locale. See directory extra/locale for
# a utility to do so. Also see the following option.
HAS_LOCALE = false
# Set this to the path of your uClibc locale file directory.
# Warning! This must be different than the glibc locale directory to avoid

# "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", at least on i386. Right now, it
# only works on i386 (and maybe m68k) because it needs sbrk.

# At present, only affects i386.

# only be included in your apps if you use regular expressions.

# This value is used by the 'make install' Makefile target. Since this
