At least I don't see it in 2.6.27-rc4, for both ia32 and amd64 UML builds.
I also had no build problems during the last few weeks.
Does you config differ a lot from the defconfig?

Are you sure you have a consistent tree? I see no declaration of
send_sigtrap in ptrace-generic.h. There is one in asm-x86/ptrace.h
but it's not at line 51.

Now I see what happened. I did have a consistent tree, but I was
doing a build via "make ARCH=um O=/usr/projects/linux/uml" --- and I
had previously built a UML tree from another source tree without doing
a "make mrproper", so /usr/projects/linux/uml/include2/asm was a
symlink to another kernel tree's include/asm directory.
It might be nice if kbuild caught the inconsistency, but this was my
bad.
