Build warning on raspbian

[hmueller01]

@andig could you verify that my change fixed the warning? Maybe someone else on a non Raspberry system could also verify this. Thanks.

Ok, my implementation breaks compiling on e.g. OSX (x86 system).

cc -I../sml/include/ -std=c99 -Wall -Wextra -pedantic -c unity/unity.c -o unity/unity.o
unity/unity.c:19:22: error: designator in initializer for scalar type 'int'
    .AbortFrame = { {.__jmpbuf = {0}, .__mask_was_saved = 0, .__saved_mask = {{0}} } }
                     ^~~~~~~~~~~~~~~
1 error generated.
make[1]: *** [unity/unity.o] Error 1

It looks like jmp_buf (the type of AbortFrame) is defined differently depending on the environment.

RaspberryPi defines it like this

/* Calling environment, plus possibly a saved signal mask.  */
struct __jmp_buf_tag
  {
    /* NOTE: The machine-dependent definitions of `__sigsetjmp'
       assume that a `jmp_buf' begins with a `__jmp_buf' and that
       `__mask_was_saved' follows it.  Do not move these members
       or add others before it.  */
    __jmp_buf __jmpbuf;         /* Calling environment.  */
    int __mask_was_saved;       /* Saved the signal mask?  */
    __sigset_t __saved_mask;    /* Saved signal mask.  */
  };
typedef struct __jmp_buf_tag jmp_buf[1];

OSX like this

typedef int jmp_buf[_JBLEN];

One solution might be a define where we can select a special case for the Raspberry (or other Linux systems?). But I haven't found one. Currently I have no idea how to solve this.

Can someone please undo my change. Tx.

on my raspi with raspian/debian 9.8 it builds fine and works fine

i think this can be closed

[devZer0]

also builds fine on debian 9.4 on raspberry, could you please close this @andig ?

also have running some influx/graphana setup with sml_server for weeks now @dingfabrik/colgone for weeks via raspberry as "bridge" between eHZ and influxdb without a problem

when this was opened, our copy of unity was already three years old,
we should probably simply have upgraded it, see #99
