kernel32 test failures under Cygwin

[Dmitry Timoshkov]

Hello all,

today I decided to play a bit with Wine compilation under Cygwin.
This time I decided to run kernel32 tests as well.

I've got the following failures:

generated.c:542: Test failed: TYPE_ALIGNMENT(*(LPWIN32_STREAM_ID)0) == 8 (expected 4)
generated: 842 tests executed, 0 marked as todo, 1 failure.
* NOTE: the same test compiled by cl.exe (MS compiler) works as expected,
* so that's most likely a gcc bug. (gcc version 3.3.1 (cygming special))

pipe: 5614 tests executed, 0 marked as todo, 4869 failures.
* NOTE: the same test compiled by cl.exe hangs forever at:
* pipe.c:285:Server done writing.

process: 373 tests executed, 0 marked as todo, 97 failures
* NOTE: the same test compiled by cl.exe gives different result:
* process: 376 tests executed, 0 marked as todo, 10 failures.

Since this is a fresh Cygwin install made from scratch I'd blame this
particular Cygwin distribution. Cygwin1.dll marked as "1.5.7-cr-0x9e"
in its version resources.

Could anybody else with a relatively fresh Cygwin or MinGW installation
try it and report the result?

P.S.
I have one more bug in Cygwin: it can't correctly handle makefiles.
So 'make' for some reason doesn't want to call 'dlltool' to produce
a .def file in dlls/d3d9 after it did run it in dlls/d3d8. Changing
order of d3d9 and d3d8 in dlls/Makefile,SUBDIRS exchanges failure
dirs. Manually chdir'ing to dlls/d3d9 and running 'make' there does help.

An old Cygwin (1.3.17) from a backup does not have that nasty bug.

Same here (GCC 3.2.3 (mingw special 20030504-1)). It appears 
that this compiler defaults to --malign-double. When I
specify --mno-align-double the test succeeds.

Both MinGW compiled tests fail here on Wine. The pipe test
also fails on Win98. These tests have in common that they
start a subprocess/thread and then should communicate or
synchronize with those. My guess is that the tests have races.

I have a semi-new cygwin install on one of the 2k servers I run so I
will make some time soon to play with it again.

Thanks
