Nope, this is on Ubuntu/Maverick/i386 32-bit.  I haven't really  
ventured into 64-bit territory. I hope you get your 64-bit float  
support nailed down, that is a great thing, that'll make the switch to  
64-bit worth it to me.

You could also just include the DLLs if you wanted.  This is not MinGW  
specific, its just that Debian, Ubuntu, Mac OS X, etc. provide those  
dynamic libs as part of the OS, while Windows does not.  For Pd- 
extended 0.43 on Windows, I included the libgcc and libstdc++ DLLs, so  
that externals built with MinGW don't need to include libgcc or libstdc 
++ either as statically linked in or as an included DLL.
