I added compile5.test. I don't think $build is part of the equation
for the purpose of this test, and the only supported $host at this
point is mingw. Is it what you had in mind?
Well, if $build is cygwin, then it'll work, because cygwin always has
cygcheck. If $build is mingw (actually "msys" in its normal 'pretend
I'm mingw' mode) then it'll work, because cmd always exists, and sed is
part of the base msys installation.
However, if $build is anything else, then it'll work IF and only IF
winepath is present. That's not a given. I don't think the test should
FAIL just because wine is not installed; I think it should be skipped.
Ok, compile5 now skips if not on mingw/cygwin and winepath is not present.
Finally, if $host is anything other than $mingw, then the tests should
be skipped, too. Right?
Right, but that was already the case I think.
Thanks for reviewing!
Cheers,
Peter

Wrap some MSVC options in the compile script.
* lib/compile: MSVC supports naming the output file, the option
is just not called -o, so transform -o into the appropriate form
for MSVC. Also wrap some other options while at it (-L, -l, -Wl,
-Xlinker and -I) and convert file names to windows form where
needed for those options to make MSVC more usable in an
autotooled environment.
* doc/automake.texi (Auxiliary Programs): Document the above
extension of the compile script.
* NEWS: Updated.
* tests/defs.in: New required entry 'cl'.
* tests/compile3.test: New test.
* tests/compile4.test: New test.
* tests/compile5.test: New test.
* tests/Makefile.am: Update.
