This may fall into the "who cares anyway?" category, but FWIW, the DMC++ IDE runs perfectly well under Wine 0.98 in Linux. While I have not exercised all features, it loads and runs perfectly without the need for native dlls.

wine c:\\dm\\bin\\scw32.exe or
wine ~/.../c/dm/bin/scw32.exe

works. Sometimes after an "execution" the top title bar drops a little and the top menu slips under the tab sheets, but it can be dragged up easily.

Users may want to tweak the WINEDLLOVERRIDES= option to use the
native comdlg32 or shell32 dll files. I don't seem to need them at this
point.

In order to allow apps that load DLLs to run, it will be necessary to edit the ~/.wine/user.reg file so that PATH includes c:\dm\bin and LIB contains c:\dm\lib. Similar to the following. (remember to use \\ when mimicking dos paths.

[Environment] 1098463510
"LIB"="c:\\dm\\lib"
"PATH"="c:\\windows;c:\\windows\\system;e:\\;e:\\test;f:\\;c:\\dm\\bin"
etc...
