2 # Site defaults for the MinGW configuration of GNU Emacs.

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.
