Yes. gcc-defaults builds fine. However, if you check the source
(debian/rules), you will see that m68k gets 4.1 versions. Since it's
less than 30 lines, I will copy it:
ifeq ($(DEB_HOST_ARCH),m68k)
no_packages += gnat
CV_CPP := 4.1.2-$(REL_NO_412)
CV_GCC := 4.1.2-$(REL_NO_412)
CV_GPP := 4.1.2-$(REL_NO_412)
CV_GOBJC := 4.1.2-$(REL_NO_412)
CV_GOBJCXX := 4.1.2-$(REL_NO_412)
CV_GCJ := 4.2.1-$(REL_NO_412)
CV_GIJ := 4.2.1-$(REL_NO_412)
CV_GCJ_HACKED := 4.1.2-$(REL_NO_412)
CV_GIJ_HACKED := 4.1.2-$(REL_NO_412)
CV_LIBGCJBC := 4.2.1-$(REL_NO_412)
CV_LIBGCJCOMMON := 1:4.2-20070303-$(REL_NO_412)
REQV_CPP = $(REQV_41)
REQV_GCC = $(REQV_41)
REQV_GPP = $(REQV_41)
REQV_GOBJC = $(REQV_41)
REQV_GOBJCXX = $(REQV_41)
REQV_LIBGCJ_BC := (>= 4.1.2-3)
REQV_GCJ = $(REQV_41)
REQV_GIJ = $(REQV_41)
LIBGCJ = libgcj7-1
LIBGCJ_PC = libgcj7.pc
LIBGCJ_SONAME = 71
endif
So, I guess only some GCJ stuff is 4.2. By the changelog, you can see
m68k is the only bad child :-(:
gcc-defaults (1.60) unstable; urgency=low
* Make GCC-4.2 the default for C, C++, ObjC, ObjC++, GFortran for
all architectures except m68k.

I don't know about gcc-4.2.2-3, but 4.2.2-4 did not build in my machine
(a cross compiler) and did not build in the buildd either
(http://buildd.debian.org/fetch.cgi?pkg=gcc-4.2;ver=4.2.2-4;arch=m68k;stamp=1196273914).
And that's for the same reason. I've checked linux-libc-dev and did not
find the cachectl.h header. So, I've decided to check in my git version
of Linux. And I could find by a log message that since 2.6.24-rc1, we
have a fix. Before I've sent a message to the list, I went to the
history and found this message:
http://lists.debian.org/debian-68k/2007/10/msg00035.html
So, it seems Geert (or Matthew Wilcox, not sure) has fixed it and it
was a reply to a message you have sent.

As I said, and as you can see by the message by Geert referenced above,
this is a very simple fix in Linux build system and only linux-libc-dev
would change, including the missing cachectl.h. Perhaps, it would be
worth to upload a new source including only this change since the last
upload?

Next time, I will give the references in the message. Sorry.
Thanks for you work,
