Has anyone recently tried to bootstrap an x86->hppa64 cross-compiler?
I'm going with cvs binutils, cvs gcc -rgcc_3_3_release.

'make boostrap'

Which under a normal gcc in x86 evaluates correclty, but under the
stage1 xgcc it doesn't. How can I, obviously without having a glibc in
64-bit userspace, analyze the value of 'sizeof(struct real_value)'?
