Subject: Fix windows NT handling for [...]_add_driver_options
X-Git-Tag: emacs-28.0.90~2727^2~475^2~5
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=c00aedb4a591fc19818ad28846b7cf03c744a730;p=emacs.git

Fix windows NT handling for [...]_add_driver_options

* Instead of conditionalizing on the wrong preprocessor flag, now use
  the right one: LIBGCCJIT_HAVE_gcc_jit_context_add_driver_option

* Also perform the driver-option-adding step on win NT, but only if
  the function is non-NULL.

* Make the function declaration for add_driver_options non-old-style.
