[ECOS] i386 pc redboot_floppy compiling error and solution

["Henry Zhu" <zhu_henry at immenstar dot com>]

Hi,

I checked out current eCos sources yesterday (01/18/2005).

Here are steps I did:

        ecosconfig new pc redboot
        ecosconfig import redboot_FLOPPY.ecm
        ecosconfig tree
        make 2>&1 | tee make.out

i386-elf-gcc complains:

current/src/main.c: In function `cyg_start':
current/src/main.c:397: invalid operands to binary &
current/src/main.c:397: warning: assignment makes pointer from integer
without a cast
current/src/main.c: In function `do_go':
current/src/main.c:598: invalid operands to binary &
current/src/main.c:598: warning: assignment makes pointer from integer
without a cast

Looking into the code, the definition of HAL_THREAD_INIT_CONTEXT seems
somehow broken.

         register CYG_WORD* _sp_ = ((CYG_WORD*)((_sparg_) & ~15));       

I changed this line to

         register CYG_WORD* _sp_ = ((CYG_WORD*)(((unsigned int)_sparg_) &
~15));

Not sure this is right, but compiling passed. Floppy image looks just
working fine.
