+Subject: [PATCH] Fix a build  error with Xorg master
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Use xf86ReturnOptValBool() in get_bool_option() instead of
+options[option_index].value.bool to fix a compiler error with
+current Xorg xserver master branch.
+
+Also use xf86GetOptValInteger() in get_int_option() and
+xf86GetOptValString() in get_str_option() for consistency.
+
+The change causes a slight performance drop during option parsing
+because the passed-in index_value is no longer used as an index
+into the options array.
+
+Instead, it's used as a token now for the standard option getter
+functions which works since the index_value to the get_*_option()
+functions are identical to the value of options[n].token in the
+passed-in OptionInfoRec array.
+
+Also rename "int option_index" to "int token" for clarity in all
+three functions.
