# It is important that CFLAGS at least specifies some optimisation,
# otherwise you may get binaries containing a lot of unused symbols
# and so be unnecessarily large. (The build deduplicates identical
# system call description, but only references to them, not their
# instantiations (which have static storage), for that it it relies
# on compiler optimisation.)
# If you know that the compiler has __builtin_ffsll([unsigned] long long int)
# which returns the index, plus 1, of the least significant set bit
# or 0 for 0, you can add -DHAVE_BUILTIN_FFSLL to CPPFLAGS; if you
# are using GCC>=3.4 or clang>=5, this is added automatically.
# Additionally, you can add -DUSE_INTERPOLATION_SEARCH to CPPFLAGS
# if you want the library to use interpolation search instead of
# binary search, this is probably a bad idea on platforms that do
# not support division natively, even on amd64, it does not seem to
# make any difference at the moment. If you add -DUSE_INTERPOLATION_SEARCH,
# you may also add `-DINTERPOLATION_SEARCH_FLOAT=long double` (default),
# `-DINTERPOLATION_SEARCH_FLOAT=double` or `-DINTERPOLATION_SEARCH_FLOAT=float`
# to specify which floating point type interpolation search should use
# if it cannot used integers; which option is best depends on the
# platform, as some platforms can work natively with any of the types
# and those `float` is most performant, and other platforms (such as
# i386) can only work natively with a specific type (`long double` in
# the case of i386) and thus performs best with that type.
