GoKawiilDeveloper revives 1998 transputer C compiler for 64-bit macOS build
Oscar Toledo G. rediscovered a 1998-era transputer C compiler he wrote, originally built with DJGPP/G++ for 32-bit DOS systems, and attempted to compile it on a modern 64-bit Macbook Air M1. He found the old code mixed integers and pointers interchangeably, lacked function prototypes, and used int instead of FILE*, all of which broke under clang since pointers are now 64-bit while integers remain 32-bit. He traces these issues back to inherited Small-C conventions, such as storing structures in byte pools and packing words as two bytes, and concludes a design change is needed to make the compiler portable.
