ext/date/extconf.rb: try_cflags("-std=iso9899:1999") [Bug #10906]
ruby itself (including numeric.c) is built with strict compile
options including -std=iso9899:1999, but ext/date is not.
By the way -std=iso9899:1999 is not only a warning option but also
changes behavior like MACRO definitions for example INFINITY.
gcc on Solaris affect this.
