Yes. Forgetting to install the binary is quite common, though.
goes without saying. put it in place by hand. difference of eight bytes between the two binaries. didn't go through the whole 'configure' / 'make' for the whole shebang, just ran make in the sqwebmail subdir after making the code change. that should be adequate, correct?
Perhaps your putchar sign-extends even if you explicitly cast the character.
Try ignoring the return value from putchar() completely.
If printf("[%d]\n", putchar((int)(unsigned char)255)); shows -1, you've got a major stdio bug.
