History; originally the memory allocation was purely the platform’s job and the only interface was the macro allocateMemoryMinimumImageFileHeaderSize which in bizarre turn used sqAllocateMemory unless it was previously defined. Yeah, I always thought it was stupid too. And I see that ‘memory’ is a usqInt in the trunk code, so ‘long’ etc really ought to have caused complaints.. .but C compilers…
Oh, I see you have static char * allocateMemoryminimumimageFileheaderSize in gcc3x-cointerp.c (as of VMMaker.oscog-eem.951 anyway) and cast it to usqInt. 

There’s lots of this stuff. As I imagine you’ve noticed. We should do better.
