I see one possibility - perhaps you have an error in your configure.ac script.  
If you mistakenly omit a newline after the use of an error-inducing construct, 
as in:

AS_ERROR([message])dnl
something

then that would result in:

as_fn_error "message" "$LINENO" 5something

and since "5something" is not an integer, that would explain the syntax error.  
But again, that would be a bug in your input file, and not in m4sh.
