Build failure in gcc-ss-0001218

[David Ronis]

A bootstrap build on an i686-linux-gnu box, with default CFLAGS, in a
clean directory, fails.  My configure flags are:

--host=i686-pc-linux-gnu --prefix=/usr --with-gnu-as --enable-shared
  --with-gnu-ld --enable-threads=posix

The log shows:

make[1]: Entering directory `/home/ronis/Project/notar/objdir/gcc'
make CC="gcc" libdir=/usr/lib LANGUAGES="c "
make[2]: Entering directory `/home/ronis/Project/notar/objdir/gcc'
(cd ../../gcc/gcc && autoheader)
autoheader: error: shell error while sourcing /tmp/ah13532/trace.sh
make[2]: *** [../../gcc/gcc/cstamp-h.in] Error 1

make[1]: *** [stage_a] Error 2
make[1]: Leaving directory `/home/ronis/Project/notar/objdir/gcc'
make: *** [bootstrap] Error 2

When I manually run autoheader (with the -d flag) trace.sh
shows the following:

#undef HAVE_ICONV_H"
configure.in:459: /usr/bin/m4: ERROR: Recursion limit of 250 exceeded, use -L<N> to change it

I'm running bash-2.04, autoheader (GNU autoconf) 2.49b and GNU m4 1.4.
