["马骅" <huamama at gmail dot com>]

hi,
 I try to build toolchains using buildroot. but when compile the
busybox, an internel compiler error show.

The target host is arm, the host is cygwin 1.5.24.
The gcc version is 4.1.2.
The busybox version is 1.1.3

Could any one give a help?

Thanks.
Below is the log for make.
