# 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.
