Hello Bruno,

thanks for the bug report.

I guess at the moment things are only consistent when the user always
adds the .exe suffix.

Is the uninstalled file .libs/iconv or .libs/iconv.exe?

The way this looks now, it will not work when used in a cross-compile
situation from a system without $EXEEXT hacks in the file matching code.

The inconsistencies you are seeing stem from the fact that cygwin's rm
won't automatically add the .exe extension (so that when both foo and
foo.exe exist, rm can be used to remove foo).  I'm not sure about
install though.  And yes, libtool should not depend upon this stuff at
all, so that the cross-compile setup works, too.

For now the right thing to do is to always use $(EXEEXT) in your make
rules.
