/*

|
|
* CONFLICT_BETWEEN_DEFINITION_OF_NULL_IN_SYS_PARAM_H_AND_STDDEF_H:
|
||
|
|
* include/pprot.h, server/dirsrv.h
|
||
|
|
* This appears to be an unpleasant interaction between GCC
|
||
|
|
* version 1.41 and the Ultrix version 4.2A system include files. The
|
||
|
|
* compiler complained about conflicting definitions of NULL in <sys/param.h>
|
||
|
|
* and <stddef.h>. The definitions are in fact the same, but with different
|
||
|
|
* spacing, which the ANSI standard says should be irrelevant.
|
||
|
|
* (Section 3.8.3, 'Macro Replacement' clearly states that:
|
||
|
|
* "An object currently defined as a macro without use of lparen (an
|
||
|
|
* object-like macro) may be reedefined by another #define preprocessing
|
||
|
|
* directive provided that the second definition is an object-like macro
|
||
|
|
* definition and the two replacement lists are identical."
|
||
|
|
* It also clearly states that, in considering whether the replacment lists
|
||
|
|
* are identical, "all white-space separations are considered identical"
|
||
|
|
* You can #define this if you encounter this bug. It will slightly slow
|
||
|
|
* down the compilation if this is left #defined, but not very much.
|
||
|
|
* I suggest you define it by modifying the definition of MACHDEF in the
|
||
|
|
* top-level MAKEFILE, since this gross kludge is necessary both in
|
||
|
|
* pprot.h and in pmachine.h.
