fail to execute the compiled Cygwin applications, it
will still exit with status zero.  This tends to confuse build systems
and test suites (including libtool's own testsuite, resulting in
spurious reported failures).  Wine support for the older Cygwin-1.5
series appears satisfactory, but the Cygwin team no longer supports
Cygwin-1.5.  It is hoped that Wine will eventually be improved such that
Cygwin-1.7 will again operate correctly under Wine.  Until then, libtool
will report warnings as described in *note File Name Conversion
Failure:: in these scenarios.

   However, 'LT_CYGPATH' is also used for the MSYS to Cygwin cross
compile scenario, and operates as expected.
