* nt/mingw-cfg.site (ac_cv_header_pthread_h) (gl_cv_sys_struct_timespec_in_pthread_h): Force to "no", to avoid picking up 'struct timespec' from pthread.h, if it is installed on the user's system. We want either the definitions from MinGW system headers, if available, or the Gnulib replacements if not. * nt/inc/ms-w32.h <struct timespec>: Don't define, as we now use lib/time.h. * lib/time.in.h: Don't let __need_* symbols affect what happens on MinGW. These symbols are defined by MinGW system headers, but we don't want that to affect whether Gnulib portions of the header are or aren't used.

# 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.
