## SIMD support
# naive approach is to just check, which SIMD-flags the compiler takes
# and use these
# drawback: while the compiler might support compilation for a specific
# SIMD instruction set, the hardware you are compiling for might not
# proposal:
# by default the configure-task should only enable flags that are known
# to work on the machine we are compiling.
# the user can override this by explicitly stating that they want the
# flag to be enabled (if possible)
# e.g. "./configure --enable-sse2" on a pentium-3 should
# produce a binary that will only run on machines with SSE2 registers
# whereas "./configure" will make a binary with only MMX enabled.
#
# but how do we test for the CPU-caps? on linux we could just read /proc/cpuinfo
# but on other OSs?
# we make it a bit complicated in order to allow people to enforce the
# compilation with a specific SIMD-instruction set, even on platforms
# that don't support it
# why? think cross-compilation
