monit&dietlibc

[Christian Hopp]

Hi!

I am trying to make monit run with dietlibc right now.  So far it runs
well without ssl.  Some tweaking was necessary...

1) autoconf (and finally configure) generates a "#define malloc
   rpl_malloc", because it is not a libc malloc.  Dietlibc's malloc is
   call malloc, thus it is undefined in monitor.h for dietlibc.

2) A handmade getloadavg is used for dietlibc.

3) All sprintf are replaced by snprintf also in foo+=sprintf(foo,...)
   situations  (=> foo+=snprintf(foo,STRLEN-(foo-buf),...).

4) There is a problem with <stropts.h>... so far is simply not
   included in case dietlibc is used...  but there is still a warning by
   configure.

5) You still have to strip the binary, in order get a small result.

Results... (striped!)

(address@hidden) ~/compile/monit/monit> ldd monit
        not a dynamic executable
Exit 1
(address@hidden) ~/compile/monit/monit> ls -la monit
-rwx--x--x    1 chopp    chopp      207644 Aug 12 12:21 monit

(-: ... I would call it pretty small for a statically linked monit.
The binary dynamically linked to glibc is 180108 bytes large.

Still todo... (might be useful for other "normal" platforms)...

1) replacement of gethostbyname against gethostbyname_r because...
   "warning: gethostbyname() leaks memory.  Use gethostbyname_r instead!"

It is ready to be synced... if accepted!
