For years now, the Project has required ANSI C (C90) to build OpenLDAP  
Software (e.g., slapd(8)) but published headers for public interfaces  
that worked with either K&R C or ANSI C (any revision).

The Project has avoided is requiring later versions of ANSI C to build  
OpenLDAP Software as support for those features is not ubiquitous.   
Some ANSI C compilers still cannot handle inline functions (use macros  
instead), unrestricted variable declarations (declare variables at top  
of block), // comments (use /* */ comments), etc.

Support for variadic macros is not terribly ubiquitous.

Yes.
