在cygwin下安装GCC的问题

nightking522

在安装的过程中系统提示如下：
$ /cygdrive/c/temp/gcc-4.0.0/configure
creating cache ./config.cache
checking host system type... i686-pc-cygwin
checking target system type... i686-pc-cygwin
checking build system type... i686-pc-cygwin
checking for a BSD compatible install... /usr/bin/install -c
checking whether ln works... yes
checking whether ln -s works... yes
checking for gcc... no
checking for cc... no
configure: error: no acceptable cc found in $PATH
请问怎么回事？
