# This configure script is *not* autoconf-based and has different semantics.
# It attempts to autodetect all settings and options where possible. It is
# possible to override autodetection with the --enable-option/--disable-option
# command line parameters.  --enable-option forces the option on skipping
# autodetection. Yes, this means that compilation may fail and yes, this is not
# how autoconf-based configure scripts behave.
#
# configure generates a series of configuration files:
#  - config.h contains #defines that are used in the C code.
#  - config.mak is included from the Makefiles.
#
# If you want to add a new check for $feature, look at the existing checks
# and try to use helper functions where you can.
