[PATCH] int10: Remove the vm86 and stub backends

2011-09-14 Thread Jamey Sharp
From: Adam Jackson vm86 has been defaulted off since 1.6, and is still a terrible idea to actually use. Time to say goodbye. The stub backend is only ever built by default on freebsd/ppc, and can't be doing any good there. The right fix is --disable-int10 if you want to not ship int10 support.

vm86 has been defaulted off since 1.6, and is still a terrible idea to actually use. Time to say goodbye. The stub backend is only ever built by default on freebsd/ppc, and can't be doing any good there. The right fix is --disable-int10 if you want to not ship int10 support. Signed-off-by: Adam
