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.
This brings in David Given's PowerPC changes, including the addition
of the modern code generator (mcg) for PowerPC.
Resolve minor conflicts in top build.lua and util/led/main.c
This header declares functions in libobject. Our programs never
included object.h, but called functions in libobject without declaring
them. So, our build system never put object.h in the include path;
any #include <object.h> would fail to find the header.
With this commit, a program may #include <object.h> if it has
modules/src/object+lib in its deps.
Declare structs in object.h so we can use them in prototypes without
gcc warning, "'struct whatever' declared inside parameter list".
Remove inclusion of ansi.h from object.h. Programs would need to
depend on modules+headers to get ansi.h in the include path.
