If MinGW doesn't complain, I agree.

-fvtable-thunks is problematic. I use gcc version 2.95.3-6 (mingw special),
(faster, smaller binaries) -fvtable-thunks is required with gcc 2,
but gcc 3 outputs a warning.
Any workaround?

Visual-MinGW generates the right makefile indeed, from user
parameters in the ".prj" file. There is three possibilities:

 - makefile.wine
 - configure.in/Makefile.am > configure script.
 - modifying params in ".prj" files.

I will change the parameters in ".prj" files, then generated
makefiles should work for both MinGW and Wine.
Though, I don't have a solution for -fvtable-thunks.

About configuration files, I started a new project called
MSYS Here, which is a MSYS loader. With it, MSYS can
be launched from Windows Explorer, the same way than
the "DOS Prompt Here" power toy.
The sources are in the MinGW CVS:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/mingw/utils/msys-here/
I'll have to write configuration files for it, as well as for WinUI,
which both Visual-MinGW and MSYS Here use.
I'm not an Autotools guru, but if it works, I'll also commit
configuration files to visual-mingw/winui. Then, I'll maybe write
configuration files for Visual-MinGW as well.

Currently, I'm not very good with Auto-stuff :(
