That looks weird, did you follow instructions that I posted? When using unpatched gcc-3.4.6 this error is due to libc change: older libc headers defined 'struct context' and gcc-3.4.6 used it. Recent libc headers no longer define this struct, so the error. However, the patch I provided effectively comments out this code, so it should be impossible to get such error.
