Wild speculation here...
A quick test shows that ./a indeed works fine inside cygwin whether the '.exe'

directly from Windows.
So... how hard would it be to provide "CYGWIN=(no)disabletransparent_exe"?***
There could a very simple utility, similar to rebaseall, which strips the .exe extension
from cygwin executables (identifiable from cygcheck or their presence in standard paths),
and which accepts additional paths to clean up. People needing the functionality would be
responsible run the utility properly (after installing new packages, don't mess with
Windows paths, etc.).
That would require no changes to any package to give the desired behavior, and as
packages change they would just fit right in (no .exe in the package ==> no
fuss).
Of course, SHTDI...

What do you do about say, Foo.c and foo.c?
The same as you do now on cygwin and on other case-preserving but
case-insensitive filesystems - treat them as identical. That's still a little
annoying, but not uncommon on unix-ish environments (OS X as one common
example) so people already are aware of it and work around it.

My point, obviously missed, was that I thought that the issue here was
that if you untar a tar which contains say a.exe and a as two different
files the later one will overwrite the former due to the way that Cygwin
treats files that end in .exe. Wouldn't you have a similar problem if
you had Foo.c and foo.c in the tar image? (Note I didn't know about that
registry setting which is interesting and which I'd venture to guess
nobody runs with).
If people "work around" the Foo.c/foo.c issue, presumably by renaming
one of the files, couldn't they likewise "work around" the a.exe/a issue?
