a7b7ce71d0 GCC build: Remove duplicate argument [#fixes #27] 
No need to specify output file in NASMFLAGS as Watcom needs it specified
in the rule. Newer versions of NASM see duplicate output file as an error.

a70f31bf61 ia16-elf-gcc: enable and fix basic warnings; don't do strict ptr aliasing for now 2018-01-11 17:50:31 -05:00

d7a05ab6cd For GCC builds use GNU make instead of wmake throughout. 
This eliminates all build-dependencies on Open Watcom.

9b5b2e7d60 Create init varieties for unsigned long helper functions. 
An INITPATCH is used to make sure the correct symbols are used.
The GCC kernel now shows the copyright string and boots a little further.

71a7d0d264 ia16-elf-gcc: provide GNU LD linker script and symbols to link kernel. 
The resulting kernel and sys.com do not work yet (kernel prints 123 only).
Some functions in sys.com are placeholders.

7bf4b77233 ia16-elf-gcc port: compile all asm files with -f elf. 
Because ia16-elf-gcc and the GNU linker do not understand OMF we
need to use ELF everywhere.
This also means we cannot use "wrt", "seg" and "call/jmp far".
Most wrt's are superfluous, and seg and call/jmp far can be
replaced by explicit ?GROUP references (to be defined in the
linker script).

fbdbc4c25c C source code changes so the kernel can compile with ia16-elf-gcc. 
Use "make all COMPILER=gcc".
Linking does not work yet with these changes.

33d707ba7f Fix compilation with MSVC 1.52c. 
Needs one more file from the c library, BSS_INIT all uninitialized
globals in config.c and a define of SEEK_SET.

44cf0a17a1 fix and enable i386 support 
This gives ~5K size reduction with bc3.1.
Today no one uses pre-i386 CPUs so there is no good
reason against having an extra optimization.
