[syslog-ng] Need help to compile syslog-ng for Solaris

[Evan Rempel]

I had similar problems compiling under AIX and had to change the macro definitions to be


#define msg_fatal(desc, ... ) msg_event_send(msg_event_create(EVT_PRI_CRIT, desc, __VA_ARGS__ ))

This is a little dangerous because it assumes that the tag1 and the tags... are
together in both the msg_fatal AND in the msg_event_create which is currently the case,
but could change in future versions.

I would have liked to make

#define msg_fatal(desc, tag1, ...) msg_event_send(msg_event_create(EVT_PRI_CRIT, desc, tag1, __VA_ARGS__ ))

but there are a few (<20) calls in the code that do not supply any paramaters, not even NULL, for the
... argument and the xlc AIX compiler does not like this. I could change these calls by adding another NULL paramater
but that makes and even more dangerous assumption that the msg_event_send function will not use the variable agrument 
list if tag1 is NULL, which is currently the case, but may change in future versions.

I think Bazsi should change the variadic macro definitions a little less gcc specific.

One more item for AIX (xlc actually) is that the calls to the preprocessor which expands these macros needs to have 
-qlanglvl=extended option suppied or the whole variadic macro thing just fails.
