It works because for -run no file formats enter the picture.  Libraries 
(like the implicit use of the C library in above hello world example) are 
dealt with via dlopen, and source files are simply compiled into memory 
blobs, without being written to files (and if going via intermediate .o 
files they are generated as ELF files, and those are understood natively 
by TCC itself).

No.

Contributions for supporting Mach-O would be welcome.
