neither command revealed what happens, but I've found the following:
running the whole autoconf unter truss -f -vall, I see that mawk tries to
open forbidden.rx in the appropriate tmp directory:

% egrep 'exec|forbidden' ac.truss
10110:  execve("/vol/local/bin/mawk", 0x0003DF08, 0x0003E2A4)  argc = 7
10110:  open("/tmp/ac10071/forbidden.rx", O_RDONLY)     Err#2 ENOENT

fails, and gives the error message reported.  This is the only reference to
this file in the whole truss output, i.e. it's never created.

Substituting gawk for mawk in a copy of the generated autoconf script, I
find:

% egrep 'exec|forbidden' ac.truss.gawk
10259:  execve("/vol/gnu/bin/gawk", 0x0003DF10, 0x0003E2AC)  argc = 7
10259:  open("/tmp/ac10220/forbidden.rx", O_RDONLY)     Err#2 ENOENT

i.e. the open fails as well, but gawk doesn't warn about this:

% ./autoconf.gawk -A .. -l /vol/gnu/src/autoconf/autoconf/tests -o- 
configure.ac:3: warning: syntax
