arm环境下编译出现下面警告的解决办法 note: the mangling of 'va_list' has changed in GCC 4.4

note: the mangling of 'va_list' has changed in GCC 4.4

I think that the warning is accurate; the mangling of va_list has indeedchanged on ARM in GCC 4.4 in order to conform to the ARM ABI specifications. There is an option to turn off warnings about PSABI issues; -Wno-psabi.  Ithink that option (if not some stronger option) should be used.
