This causes clang to give fewer warnings of implicit declarations of
functions.
In mach/pdp/cv/cv.c, rename wr_int2() to cv_int2() because it
conflicts with wr_int2() in <object.h>.
In util/ack, rename F_OK to F_TRANSFORM because it conflicts with F_OK
for access() in <unistd.h>.
This unbreaks my build in OpenBSD. The old `long lseek()` conflicts
with `off_t lseek()` in OpenBSD headers, because long and off_t are
different types. Commit b4df26e caused "system.h" to include some
headers where OpenBSD declares lseek().
Manuals for lseek() say to #include <unistd.h>. Do so to be portable
to systems where other headers don't declare lseek().

This got caught by MALLOC_OPTIONS=S in OpenBSD. The B compiler filled
the buffer while compiling hilo.b. Then realloc moved the buffer and
unmapped the old buffer. The compiler tried to read the old buffer
and segfaulted.
With this change, I built and ran ack on a big-endian PowerPC Linux
machine. I used gcc 4.9.4 to build ack, and I only built the linuxppc
back end.
Before this change, wr_ranlib() corrupted a value by changing it from
0x66 to 0x66000066. This value was too big, so led made a fatal
error, "bad ranlib string offset".
I made a syntax error in some .e file, and em_encode dumped core
because a 64-bit pointer didn't fit in a 32-bit int. Now use stdarg
to pass pointers to error() and fatal().
Stop using the number of errors as the exit status. Many systems use
only the low 8 bits of the exit status, so 256 errors would become 0.
Also change modules/src/print to accept const char *buf
Drop dependency on <ansi.h> in modules+headers; assume that compiler
knows ANSI C89.
Add missing dependency from print to string; #include <ack_string.h>.
Because <print.h> had commented out the declarations of sys_lock() and
sys_unlock(), I now stop building lock.c and unlock.c.
Some of these functions were slightly different from libc:
- This strncpy() didn't pad the buffer with '\0' bytes beyond the end
of the string; libc does the padding. This string.3 manual said
that this strncpy() does "null-padding", but it didn't.
- This strcmp() and strncmp() compared using char (which might be
signed); libc compares using unsigned char.
Edit build.lua for programs losing their private assert.h, so they
depend on a list of .h files excluding assert.h.
Remove modules/src/assert; it would be a dependency of cpp.ansi but we
didn't build it, so cpp.ansi uses the libc assert.
I hope that libc <assert.h> can better report failed assertions. Some
old "assert.h" files didn't report the expression. Some reported a
literal "x", because traditional C expanded the macro parameter x in
"x", but ANSI C89 doesn't expand macro parameters in string literals.
