Hi,
This patch aims to improve ansi C compatibility. That is, on the issues
addressed by this patch, bcc does not flag any error, but any ansi C
compiler will produce an error and will terminate compilation.
The errors corrected with this patch were found attempting to build ELKS
using gcc (instead of bcc). This patch produces a small increase in code
size building ELKS using bcc (less than 16 bytes). However, the system
start flawlessly and with no apparent differences.
The Image builded without errors. The kernel was tested with QEMU and
dioscuri emulators. Also in a PPro pc booting from floppy.
Greetings,
Juan
