the code being generated does not require an executable stack.

Also, add target-specific code to make use of this on Linux
on x86.

pedantic error.  Perhaps I should add a class of 'extension' that is

a) correct rejection of ',' in pp expressions.
b) the precedence of ',' was wrong w.r.t. ?:.

Thanks again to Neil for finding these and providing testcases.
