I should have been clearer. I will try to do so now.

Well it depends on the standard and the level of compliance that each
standard puts to things. Some standards can consider you less
compliant because they consider a tool which does not meat the rest of
its demands as cheating. Other standards do a scaled score system
where your minimal compliance (aka 1 point out of N) is that a tool
exists. Having read some of the POSIX threads on bash not being sh
enough for POSIX compliance.. I don't know where flex not being 100%
compliant makes things better or worse.

Which is why I wanted to see where this was going. Are these fixes
just looking for low hanging fruit to be POSIX compliant, or are these
needing larger amounts of resources to be 'compliant'? If the
flex->lex link fails some sort of POSIX test, are people going to need
Cygwin porters to fix those? Also is there an easy line for "this is
compliant enough?"
