I agree with that suggestion. On Linux, there are limitations given by execve(2) system call. I observe that Clang/LLVM people might disagree with it. One of the issues is that we could want several C files compiled into one shared library. Another of the issues is that we could want to specify different code generation or optimizations. Perhaps the second non comment line could be some #pragma. GCC allows the standard input to be used. Maybe a possibility might be to have a /usr/bin/gcc-stdin executable? Observe that tinycc (a quick non-optimizing open source C compiler) already has the wanted feature https://en.wikipedia.org/wiki/Tiny_C_Compiler > TCC-DOC(1) Tiny C Compiler > TCC-DOC(1) > > NAME > tcc - Tiny C Compiler > > SYNOPSIS > usage: tcc [options] [infile1 infile2...] [-run infile > args...] > > DESCRIPTION > TCC options are a very much like gcc options.
