   4 # This file's purpose is to short-circuit configure-time tests for
   5 # which we want to provide the results instead of letting the
   6 # 'configure' script do that.  This is mainly for features that
   7 # 'configure' tests that are implemented as part of Emacs sources, not
   8 # as part of system libraries.  The idea is to set shell variables
   9 # that appear to the script as cached values.
  10 #
  11 # For each header file foo.h you want to supply test results, set the
  12 # value of a shell variable ac_cv_header_foo_h.  The value should be
  13 # yes if the header is deemed to exist, no otherwise.  Or it could be
  14 # something else, if the value computed by 'configure' requires that.
  15 # In general, since nt/msysconfig.sh instructs GCC to use header files
  16 # in nt/inc, you should not need to futz with header file tests.  But
  17 # there are exceptions, like with getopt.h below (which is a MinGW
  18 # system header, but we do not want to use it).
  19 #
  20 # For each library function foo you want to supply test results, set
  21 # the value of a shell variable ac_cv_func_foo.  Again, the value is
  22 # determined by what 'configure' expects; sometimes it could be "not
  23 # needed" or whatever, see the examples below.  In addition, you may
  24 # need to set the various gl_cv_* variables for those tests that come
  25 # from gnulib.
  26 #
  27 # In short, examine the test in 'configure' and push the knobs that
  28 # are necessary to steer the test in the direction you need, by
  29 # judiciously setting variables that control the test results.
