C99 在 定義了, include 就可以使用。

int8_t      int16_t      int32_t      int64_t
uint8_t     uint16_t     uint32_t     uint64_t

-nostdinc
        Do not search the standard system directories for header files.
        Only the directories you have specified with -I options (and the
        directory of the current file, if appropriate) are searched.

-nostdinc 不會去搜尋標準 C include file path。
