Removed a lot of OS specific #ifdefs. Lots of dependend multimedia cleanups. * [loader/pe_image.c] Enhanced comment, added missing reference count increase. * [ole/compobj.c] Replaced broken StringFromGUID2 by working one. * [misc/winsock.c] SO_LINGER uses unsigned 16 bit in Win16 and Win32, but unsigned int (32bit) for UNIX. * [memory/global.c] Allow realloc for lockcount 1 too. Fri Apr 10 15:27:34 1998 Morten Welinder <terra@diku.dk> * [graphics/x11drv/text.c] Handle control characters in trace.

|
|
*
|

* If debugmsg(relay) is OFF:
|
|
* ... ...

* (esp+4) args
|
|
* (esp) return addr to caller

* (esp-4) function entry point

* If debugmsg(relay) is ON:

* (esp+8) args
|
|
* (esp+4) return addr to caller
|
|
* (esp) return addr to DEBUG_ENTRY_POINT
|
|
* (esp-4) function entry point
|
|
*
|
|
* As the called function might change the stack layout
|
|
* (e.g. FT_Prolog, FT_ExitNN), we remove all modifications to the stack,
|
|
* so that the called function sees (in both cases):
|

* (esp) return addr to caller

* ... >128 bytes space free to be modified (ensured by the assembly glue)

*
|
|
* NOTE: This routine makes no assumption about the relative position of
|
|
* its own stack to the stack pointed to by ESP_reg(&context),
|
|
* except that the latter must have >128 bytes space to grow.
|
|
* This means the assembly glue could even switch stacks completely
|
|
* (e.g. to allow for large stacks).
