Then they're unix, and they should compile fine ...
betty:/usr/oboe/ptb% gcc uudecode.c
uudecode.c:46: parse error before string constant
uudecode.c:46: warning: data definition has no type or storage class

Oh - that's a silly identifier.
__FBSDID("$FreeBSD: src/usr.bin/uudecode/uudecode.c,v 1.49 2003/05/03 19:44:46 obrien Exp $");
Comment it out.

Nothing much. It expects to be linked against some library. A quick
grep through my library symbols in /usr/lib comes up with
betty:/usr/oboe/ptb% strings --print-file-name /usr/lib/*.a | grep setmode
/usr/lib/libvga.a: vga_setmode
/usr/lib/libvga.a: vga_setmodeX
/usr/lib/libvga.a: vga_setmode
/usr/lib/libvga.a: vga_setmodeX
/usr/lib/libvga.a: vga_setmode
/usr/lib/libvga.a: setmode
/usr/lib/libvga.a: et4000_setmode
...
so let's try -lvga, though this seems silly! The code expects setmode
to return a void * which itthen uses as a handle in all subsequent ops.
I would suspect it's a file manipulation library. It's called as
handle = setmode(p)
where p is a buffer ... containing the "mode" in a uuencoded file.
Heck, why should we care. Let's just ignore the mode. Comment it all
out. Set mode to 0644 like always.
betty:/usr/oboe/ptb% gcc uudecode.c

Oh, that's a warning message. Try something like
#define warnc(a, b, c...) { errno = a; warn(b " (%p)", c); }
betty:/usr/oboe/ptb% gcc uudecode.c

Hmm ...
n = b64_pton(inbuf, outbuf, sizeof(outbuf));
if (n < 0) break;
Oh - the bad news is that this code desn't conatin the actual routine
that does the translation of 4 words of 6-bit ascii input to 3 bytes
of binary output! Look for more source elsewhere on the site.
But why are you doing all this? uudecode and uudecode is a perfectly
normal part of linux!
