Yes, other applications have already had similar issues, and we've fixed 
that by recoding them to not assume that SIGSTKSZ is an integer constant 
expression. See, for example, this patch to Gnulib last September:

https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=f9e2b20a12a230efa30f1d479563ae07d276a94b

This patch appears in the latest GNU grep, for example.
