uz cbefb85d47 Fixed a problem reported by Greg King. structs returned from functions in the 
primary register are actually rvalues and need special treatment.

cuz 9174f65e54 Make much more usage of dynamic strings (StrBufs) instead of char* and 
friends. Since names and other strings are now StrBufs in many places, code
for output had to be changed.

This allows use of macros in the file spec and is a requirement of the C
standard.

cuz 84706bd2d5 Fixed portability problems with va_copy. In three places, calls to fstat 
had to be replaced by calls to stat, because fileno is no longer available
when forcing the compiler into pure c89 (or c99) mode.
