Problem building httpd

[Ewald Wasscher]

Hello all,

I just anxiosly tried to build httpd from the new 0.17 release with cgi 
support enabled. Unfortunately it fails:

bash-2.05a$ make httpd
nasm -w+orphan-labels -w+macro-params -i../inc/ -f bin -D__LINUX__ 
-D__KERNEL__=24 -D__SYSCALL__=__S_KERNEL__ -D__OPTIMIZE__=__O_SIZE__ 
-D__ELF__ -D__ELF_MACROS__ httpd.asm
httpd.asm:282: short jump is out of range
make: *** [httpd] Error 1

As I know next to nothing about assembler I wonder how one should fix 
that (replace jb with jmp?)

For nasm 0.98.

Hah, I guessed so (I do remeber a little: I once bought a book on
assembler in the days that a 80286@12mhz was a very fast pc)

You got it in private mail, it's httpd.asm from the asmutils 0.17 release.

Replace 'jb' with 'jb near'.
This will be fixed in the next release.

With nasm 0.98.34 it builds fine though.
