The only difference was "--without-gcc". (I am not setting the
emacs_cvs_speed_t variable; neither is anything in the system, according to
env | grep speed.)
Note the configure script location marked with @@@ below. The "if" part
does set the speed variable; the "else" part does not. And, since I am not
setting it myself, I believe this is why the variable is not being set.
In other words, I believe that, when using the "--without-gcc" option, the
"if" part is not being run and therefore the variable is not being set.
echo $ac_n "checking for speed_t""... $ac_c" 1>&6
echo "configure:3020: checking for speed_t" >&5
if eval "test \"`echo '$''{'emacs_cv_speed_t'+set}'`\" = set"; then
echo $ac_n "(cached) $ac_c" 1>&6
else
cat > conftest.$ac_ext <<EOF
#line 3025 "configure"
#include "confdefs.h"
#include <termios.h>
int main() {
speed_t x = 1;
; return 0; }
EOF
if { (eval echo configure:3032: \"$ac_compile\") 1>&5; (eval
$ac_compile) 2>&5; }; then
rm -rf conftest*
@@@ emacs_cv_speed_t=yes
else
echo "configure: failed program was:" >&5
cat conftest.$ac_ext >&5
fi
rm -f conftest*
fi
echo "$ac_t""$emacs_cv_speed_t" 1>&6
if test "$emacs_cv_speed_t" = yes; then
cat >> confdefs.h <<\EOF
#define HAVE_SPEED_T 1
EOF
fi
Is there anything else I might be able to check?

Can you talk with them and together figure out what's really going on?

That code comes from configure.in:
dnl Check for speed_t typedef.
AC_CACHE_CHECK(for speed_t, emacs_cv_speed_t,
AC_TRY_COMPILE([#include <termios.h>], [speed_t x = 1;],
emacs_cv_speed_t=yes, emacs_cv_speed_t=no))
if test $emacs_cv_speed_t = yes; then
AC_DEFINE(HAVE_SPEED_T, 1, [Define to 1 if `speed_t' is declared by
<termios.h>.])
fi
Since that variable is defined either to no or to yes just above
(in the absence of a cached value), I don't see a need for double
quotes, unless he's doing something strange:
-- he is using a corrupted cache file, or
-- he has set emacs_cv_speed_t to the empty string in his environment
