zsh on QNX4

["Philippe Robin" <probin@xxxxxxx>]

Hi ,

I got zsh running on QNX 4.25 operating system. I have included the few
modifications I did to get it to work at the end of this mail if you want to
incorporate this...

Feel free to contact me if you have any queries.

Thanks,

Philippe

-----------------
halloc() is already defined on QNX with the following prototype:
void __huge *halloc( long int numb, size_t size );

so the halloc() function must either be renamed in files where it
is used so that it doesn't clash with the system one or alternatively
use the system function.

The files concerned are:
mem.c, subst.c, utils.c, zle_hist.c, zle_misc.c, zle_tricky.c,
zle_utils.c, zle_word.c
