Hi all,
I have revised and slightly rewritten the DLL-support for GRX. The main trick
for making the DLL and the import-lib is the option
gcc -shared -Wl,--export-all -Wl,--out-implib= libgrx.dll.a -o GRX.dll $(ALL_O) $(ADDON_LIBS)

and linking the application against libgrx.dll.a

Linking an application directly against the DLL is currently not possible because constructs like

struct foo * const FooInfo = &_FooInfo;
struct foo _FooInfo = { ... };

Accessing _FooInfo in the DLL works OK, but FooInfo poins to some distant stars.

To fix this one would need dllimport/dllexport decorations for FooInfo that clutter up the
source code.

For other changes see the changelog below.

Ths systag naming conflicts with Dimitar's patches from friday :-(

Ciao

<<thdgrx.zip>>

* include/grx20.h: Added define for __CYGWIN32__ and removed
  the old equality __CYGWIN32__ is also __WIN32__. This is
  required to have the X11 driver in cygwin.

* makedefs.grx: Added systags for CYGWIN and MinGW with CYGWIN
  compiler.

* src/fdriver/ftable.c: Added "ifdef" for native driver in Cygwin

* src/include/grxdebug.h: Is __GNUC__ stil in use for any gcc? Added
  __CYGWIN32__ and __MINGW32__, but another test may make more
  sense.

* src/utils/dbgprint.c: dito

* src/mouse/input.h    : Replaced __WIN32__ by __WIN32__||W32NATIVE_DRIVER

* src/vdrivers/vtable.c: Replaced __WIN32__ by __WIN32__||W32NATIVE_DRIVER

* src/vdrivers/vd_win32.c: Revised reset(). Neiter PostMessage, nor
  PostThreadMessage could convince the windowThread to terminate.
  TerminateThread() does.  Not elegant, but effecient.
  Made windowThread static.

* src/include/libwin32.h: Removed windowThread.

* test/demogrx.c: Added C32 for version=...386_CYG32

* test/speedtst.c: Removed inclusion of <values.h> because it prevailed compilation
  under Cygwin and file is empty for the MinGW compiler.

* test/keys.c: Also the W32 windows drivers need a graphics mode to initialize
  keyboard and mous functions.

TODO:
 Move Library names to makedefs.grx.
