linker errors if multiple C files have same name

[Waqar144]

when using c sources mixed with c3 sources, if there are two C files in different directories with same name then it results in linker errors

Yes, that's probably rather inevitable using the current scheme where all .o files are placed in the same directory. Possibly we could rename them?

Yes, that'd be good. I'd suggest just suffixing a number for the duplicates. The compiler can print note to stderr about the duplication and the new name.
