Two porting issues -- Temporary classes and void pointers

[Alberto23]

Well, I am porting C++ code from Visual Studio C++ to GCC.

I found two main issues that bother me enough to write about them.

(1.0) Temporary classes

     {    buf << class_A(); }                   // does not compile on GCC,
yak
     {    Class_A tmp;    buf << tmp; }   // compiles on GCC

So it seems GCC does not want us to use direct notation of temporary
classes.
Consider: { buf << A() << B() << C(); } which will not be allowed by the
samaritan


(2.0) void pointers

    {  char* ap;   void* vp = ap; }     // does not compile on GCC, yak
                                                      // but in VS++ void*
can receive all pointers.

     { vp = (void*) ap; }  // the good samaritan wants you to cast even the
amorphic void*; yak


If you know of some way to teach the GCC to work like VS++ with these issues
-- would be delighted to hear from you.
