processor compatibility when building packages

This topic came up about a year ago on this list:
and I've recently raised it again on mingw lists.
Looking at cygwin's spec file it says:
To me that means that, unless user overrides with command line -march or
-mcpu option, code is tuned for i686. To get that into the specs file, one
has to either configure gcc so that TARGET_CPU_DEFAULT=3 (=pentium) or pass
that define to make when building gcc.
That interpretion is different from the conclusion that was posted in the
message pointed to above, which says that cygwin-produced code will run on
any i86 arch.
I'm not talking about the platform triplet moniker -- that I realise is
just a name. I'm asking: Has anyone complained that cygwin-built apps fail
on i386 but not on i686?
