So assigning a void pointer to a non-void pointer is legal in C and illegal

situations in the past. Also, there were some C compiler(s) years ago that
required these casts (can't remember which).
That would be interesting to know.
The historical problem I remember was pre-ANSI C89, when compilers either didn't
have (void *) so had malloc return (char *) or didn't have a header providing a
declaration of malloc before C added function prototypes. I don't think any
such compilers can still be used to build Mesa.
That's probably true. In the early days I was using HP, IBM, IRIX,
Sun, DEC, etc. compilers and they all had their idiosyncrasies.
Linux/gcc was one of the later platforms for Mesa, actually.
I don't think we've been 100% consistent about casting the results of
malloc() and nobody's complained so it's probably fine.
And I don't recall who/why someone needed to compile all of Mesa as C++.
