Hello John, I like very much the idea to make tcc POSIX compliant. I still work on C/C++ normalization in AFNOR group and worked on different groups including ISLISP and POSIX, so standards matter for me :).
Please, also consider that neither gcc nor clang support space after -O: $ clang -O 3 cspy.c -l m clang: error: no such file or directory: '3' $ clang -O 3 cspy.c -l m clang: error: no such file or directory: '3' I think that nobody will refuse a patch that fully supports POSIX compatible option as long it does not break gcc/cl compatibility. libxnet and libtrace may be especially checked by configure (new --posix) option and dropped from command line if not supplied by the system. An alternate solution is to make almost empty libxnet.a and libtrace.a when --posix option is set by ./configure Can you try to propose something?

In the meantime, tcc can't be used for building. There is concern that small compilers all have their own caveats, and tinycc's seem minor. POSIX says a space after -l—and all flags for that matter—is okay, but tcc doesn't accept this: $ tcc hello.c -l c tcc: error: library '' not found It also doesn't handle a space after -O. Fortunately -D, -I, -L, and -U all tolerate this. For completeness here's another discrepancy: * tcc errors with -lxnet or -ltrace, but so do gcc and Clang. Please let me know if there's anything I can do to help, and thanks for working on tinycc!
