2.1.27rc4: two (minor) issues with autotools scripting

[makr]

Hi *,

these are probably no show stoppers, but I thought I'd list it, maybe someone has a quick fix ...

1) providing --with-opie or - as in my case - --without-opie always produces a warning: configure: WARNING: unrecognized options: --without-opie

2) on HP-UX a test produces unexpected output:

checking for underscore before symbols... "conftest.c", line 1: warning #2951-D: return type of function "main" must be "int"
  void main(){int i=1;}
       ^

no

-- makr

I don't get this warning on Fedora 26 with autoconf 2.69

Does this help?

Sorry, it took a while until I could test it. But yes, indeed, your changes will fix both issues!
