/bin/sh: autoheader: command not found

[Iain McClatchie]

I made a new working directory for egcs.
Then I downloaded CVS-1.9.24, then

cvs login
cvs co -regcs_1_1_prerelease egcs
mkdir objdir
cd objdir
../egcs/configure
make bootstrap
... lots of output ...
Bootstrapping the compiler
make[1]: Entering directory `/var/iain/egcs/objdir/gcc'
make CC="gcc" libdir=/usr/local/lib LANGUAGES="c "
make[2]: Entering directory `/var/iain/egcs/objdir/gcc'
cd ../../egcs/gcc && autoheader
/bin/sh: autoheader: command not found

... and it stopped almost immediately.  The shell script "missing"
claims to be a stub for autoheader here, but I couldn't determine how
"missing" would get called.  "missing" claims it should only be needed
if I've been hacking on configure.in, which I haven't touched.

This must be a simple problem.  Does anyone recognise it?
