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.

Indeed I have tried without following your instructions and patch.

Now that I see that there is a reason for your patch, I will retry by following your instructions. ;-)
