Remove some declarations (not all correct) and #include <errno.h>,
<time.h>, and <unistd.h> to get the correct declarations.
Disable mount(2), umount(2), and stime(2) because BSD (around
4.3BSD-Reno) lost compatibility with these Unix v7 functions.
From my request at https://github.com/kstenerud/Musashi/pull/31
There was a conflict between Musahi's uint and OpenBSD's uint:
$ cc -o m68kmake m68kmake.c
$ ./m68kmake
$ cc -DM68K_COMPILE_FOR_MAME=0 -c m68kcpu.c

The code included <X11/Xfuncproto.h> only for _X_ATTRIBUTE_PRINTF,
which tells some compilers to check the printf format string. Remove
so ACK doesn't need any X11 headers.
Some machines don't have the X11 headers, or they need a flag like
-I/usr/X11R[67]/include to find them.
This changes the BDOS call from CPM_BDOS_CONSOLE_INPUT to
CPN_BDOS_READ_CONSOLE_BUFFER. This allows commands like ^H to delete
characters and ^C to exit to CCP. This is more like how Unix read(2)
uses canonical mode of termios to read a line.
This change has a disadvantage: the user buffer to read(2) must now be
large enough for an entire line. This is because CP/M, unlike Unix,
lacks a kernel buffer to hold the rest of the line. If you use a
buffered input library like stdio to call read(2), then it works; but
if you try to read part of a line or a single character, then it
doesn't work.
Change from `uread(0, c, 1)` to `read(c)`, so input goes through
libpc's buffer. If input is a tty in Unix, this reduces the number of
read(2) system calls from one per character to one per line.
This change will become necessary in CP/M when I enable the line
editor.
Add a variable %{ackldflags} so I can pass `-fp`. This change seems
to cause the build to relink every ackprogram, because the link now
needs to use %{ackldflags} even if the flags are empty.
mandelbrot_c_cpm runs in YAZE-AG; startrek_c_cpm doesn't run because
it doesn't fit in the 16-bit address space.
This drops 124 bytes from the mandelbrot command (from 15015 to 14891
bytes) but has almost no effect on performance; the command takes
about 144 seconds (in YAZE-AG) both before and after optimizing libfp.
