+       Use C99 blanks as default argv separators, per issue [#2329].
+
+       * setargv.c [_ISOC99_SOURCE]: Require it.
+       (__mingw32_setargv): Separate command line arguments based on...
+       [(quoted == 0) && isblank( c )]: ...this condition, instead of on...
+       [(quoted == 0) && isspace( c )]: ...this, so that only blanks, rather
+       than any whitespace characters, serve as default argument separators.
