Build errors on Haiku

[roryrjb]

Hey, I was just investigating compiling on Haiku for a couple of simple projects I am working on and it doesn't seem straightforward from a lib point of view. Anyway I tried oksh and there are some errors and as you may have the interest and patience (as per #39) I thought I'd share my initial findings and maybe we can somehow figure this out together.

Here's the first issue:

~/Repos/oksh> cc -DEMACS -DVI -w   -c -o edit.o edit.c
edit.c: In function 'x_mode':
edit.c:176:28: error: 'VWERASE' undeclared (first use in this function); did you mean 'VERASE'?
   edchars.werase = cb.c_cc[VWERASE];
                            ^~~~~~~
                            VERASE
edit.c:176:28: note: each undeclared identifier is reported only once for each function it appears in
edit.c:180:11: error: 'VLNEXT' undeclared (first use in this function); did you mean 'LEXIT'?
   cb.c_cc[VLNEXT] = _POSIX_VDISABLE;
           ^~~~~~
           LEXIT
edit.c:182:11: error: 'VDISCARD' undeclared (first use in this function); did you mean 'S_ISCHR'?
   cb.c_cc[VDISCARD] = _POSIX_VDISABLE;
           ^~~~~~~~
           S_ISCHR

...and here's the compiler:

~/Repos/oksh> gcc -v

If wrapped those issues in: #ifndef __HAIKU__ and then got the following:

Hi. I just committed support for Haiku.

Some caveats:

1. The fc command requires /bin/ed. I see that HaikuPorts has an ed package, but when I install it, it does not add anything! So you can't use any of the fc features (you can press the up and down arrows to scroll through your history).
2. The Haiku ncurses package does not seem to include development headers. As a result, ^L to clear the terminal won't work. The external clear command works fine.

@ibara awesome, cheers!
