Build without optimization is broken again

[Pavel Roskin]

Hello!

Build without optimization is broken again in CVS:

gcc -o wine -Wl,--section-start,.interp=0x3c000100 main.o  -L../dlls
-lntdll.dll -L../libs/wine -lwine -L../libs/unicode -lwine_unicode
-L../libs/port -lwine_port
../dlls/libntdll.dll.so: undefined reference to `SetLastError'
../dlls/libntdll.dll.so: undefined reference to `GetCurrentProcessId'
../dlls/libntdll.dll.so: undefined reference to `GetCurrentThreadId'

GetCurrentProcessId() and GetCurrentThreadId() are referenced by
dlls/ntdll/virtual.c and dlls/ntdll/server.c respectively because they
don't include ntdll_misc.h header that has replacement includes.

SetLastError() is used by the set_status() wrapper in dlls/ntdll/heap.c.
I believe NtCurrentTeb()->last_error is valid even for gcc x86 builds.
At least it's used unconditionally in LdrInitializeThunk(), file
dlls/ntdll/loader.c.

ChangeLog:
    * dlls/ntdll/server.c, dlls/ntdll/virtual.c:
    Include ntdll_misc.h to suppress wrong dependencies
    when building Wine without optimization.
    * dlls/ntdll/heap.c:
    Define set_error unconditionally to eliminate dependency
    on SetLastError().
