- moved ne2k presence check to devices.cc
- added special make rules for the ne2k and the lowlevel network support
- added macro for the debug feature of the ne2k
- leave just the two configurations that I plan to build binary RPMs with:
one is conservative with just X11 and the options we used before,
and the other includes plugins, lots of display libraries, etc.
- My previous rev to dbg_main.cc caused the debugger to fail when readline
was disabled. With these changes I have tested more thoroughly and it works
with readline enabled or disabled, and with wxWindows enabled and disabled.
- The Bochs debugger uses BX_WITH_WX to decide to change to wxWindows debugger
behavior: sending a synchronous message to the config interface to get a new
command, sending all dbg_printf output to the config interface, deciding
whether to trap control-C, etc. But now that it's possible to compile with
BX_WITH_WX and BX_WITH_other_things, this isn't quite right anymore. With
this change, we now use calls to a new method SIM->is_wx_selected() to decide
which behavior to use. This method is equivalent to checking if the display
library variable is set to "wx", but it's implemented in such a way that it
only has to check a boolean for each call to SIM->is_wx_selected().
- in siminterface.cc, init some local variables to 0 to avoid compile
warnings.

For a whole lot of configure options, I put #if...#endif around code that
is specific to the option, even in files which are normally only compiled
when the option is on. This allows me to create a MS Visual C++ 6.0
workspace that supports many of these options. The workspace will basically
compile every file all the time, but the code for disabled options will
be commented out by the #if...#endif.
This may one day lead to simplification of the Makefiles and configure
scripts, but for the moment I'm leaving Makefiles and configure scripts
alone.

reports that on some Linux systems, once you restart the font server
you have to restart X as well. At least with this change it only happens
once, not every time you install.

- configure script adds -DBX_PLUGIN_PATH="${plugdir}" to CFLAGS/CXXFLAGS
in the Makefile.
- in main.cc, if plugins enabled and the environment variable LTDL_LIBRARY_PATH
is not set, then it gets set to the value supplied by BX_PLUGIN_PATH.

- argc was returning the wrong number of args. Now I treat null and space
the same way, except that null causes the loop to exit.
- change "extern "C" int WinMain" to "int WINAPI WinMain".
- in WinMain pause for the user to read the screen before making it disappear.
This is very useful when there was an error during startup because otherwise
you can't read it. However we'll probably want to disable it when the
user actually asked for Bochs to quit.

For years we have been writing beyond the end of this array in the VGA code:
bx_bool vga_tile_updated[BX_NUM_X_TILES][BX_NUM_Y_TILES];
and doing who-know-how-much damage to other memory structures in the process.
I changed every reference to vga_tile_updated[][] into calls to two macros
GET_TILE_UPDATED and SET_TILE_UPDATED, and defined the macros to check
the bounds of the array before referencing it. At first I used an
assert, then a panic, then an error, and now I'm not printing any message
at all because there were thousands and thousands of messages during
a boot of win95 when it's updating the win95 logo screen.
- I couldn't resist cleaning up a few confusing-looking things like
"if (condition) { // }". There are no functional changes except for
bounds checking on the vga_tile_updated array.
needs to include the .o's and .a's that are part of the Bochs source code
so that it can create a list of Bochs symbols that need to be exported.
I started out using the same list as the link line, but dlltool
doesn't accept all the same options as the link such as -I and -L.
