With attached demo patch, ^C will interrupt the open() call for me, *when*
I use clang or tcc as compiler.  But with gcc... nothing happens.  :|

$ clang --version | head -1
clang version 6.0.0-1ubuntu2 (tags/RELEASE_600/final)

$ tcc -v
tcc version 0.9.27 (x86_64 Linux)

$ gcc --version | head -1
gcc (Ubuntu 7.4.0-1ubuntu1~18.04) 7.4.0
