Re: slightly off topic: gnu make and VC++



Since you have /NODEFAULTLIB:"libcd.lib" I'm assuming maybe you did a
debug build on some objs?  THis would make sense, since operator new() is
defined (overloaded, really) in the debug version of the library because
it checks some things and sets the memory to 0xFD so that you may find
uninitialized memory problems.  If you say cl -?, the last things will be
the -Mx options.  You may need to add one of these to your command line.
LIBC and LIBCD are not compatible.
