configure:3855: gcc -V >&5 gcc: error: unrecognized command line option '-V'

一般的：

configure:3866: $? = 0
configure:3855: gcc -V >&5
gcc: error: unrecognized command line option '-V'
gcc: fatal error: no input files
compilation terminated.
configure:3866: $? = 1
configure:3855: gcc -qversion >&5
gcc: error: unrecognized command line option '-qversion'; did you mean '--version'?
gcc: fatal error: no input files
compilation terminated.      

類似錯誤還有：

error: ac_nonexistent.h: No such file or directory,      

出現這樣的錯誤，不必理會。繼續向下找。
