# Site defaults for the MinGW configuration of GNU Emacs.
#
# This file's purpose is to short-circuit configure-time tests for
# which we want to provide the results instead of letting the
# 'configure' script do that. This is mainly for features that
# 'configure' tests that are implemented as part of Emacs sources, not
# as part of system libraries. The idea is to set shell variables
# that appear to the script as cached values.
#
# For each header file foo.h you want to supply test results, set the
# value of a shell variable ac_cv_header_foo_h. The value should be
# yes if the header is deemed to exist, no otherwise. Or it could be
# something else, if the value computed by 'configure' requires that.
# In general, since configure (when invoked from an MSYS environment)
# instructs GCC to use header files in nt/inc, you should not need to
# futz with header file tests. But there are exceptions, like with
# getopt.h below (which is a MinGW system header, but we do not want
# to use it).
#
# For each library function foo you want to supply test results, set
# the value of a shell variable ac_cv_func_foo. Again, the value is
# determined by what 'configure' expects; sometimes it could be "not
# needed" or whatever, see the examples below. In addition, you may
# need to set the various gl_cv_* variables for those tests that come
# from gnulib.
#
# In short, examine the test in 'configure' and push the knobs that
# are necessary to steer the test in the direction you need, by
# judiciously setting variables that control the test results.
