  This file provides platform-dependent definitions for all Netpbm
  libraries and the programs that use them.

  The make files generate pm_config.h by copying this file and adding
  other stuff.  The Netpbm programs #include pm_config.h.

  Wherever possible, Netpbm handles customization via the make files
  instead of via this file.  However, Netpbm's make file philosophy
  discourages lining up a bunch of -D options on every compile, so a 
  #define here would be preferable to a -D compile option.

/* Switch macros like _POSIX_SOURCE are supposed to add features from
   the indicated standard to the C library.  A source file defines one
   of these macros to declare that it uses features of that standard
   as opposed to conflicting features of other standards (e.g. the
   POSIX foo() subroutine might do something different from the X/Open
   foo() subroutine).  Plus, this forces the coder to understand upon
   what feature sets his program relies.

   But some C library developers have misunderstood this and think of these
   macros like the old __ansi__ macro, which tells the C library, "Don't 
   have any features that aren't in the ANSI standard."  I.e. it's just
   the opposite -- the macro subtracts features instead of adding them.

   This means that on some platforms, Netpbm programs must define
   _POSIX_SOURCE, and on others, it must not.  Netpbm's POSIX_IS_IMPLIED 
   macro indicates that we're on a platform where we need not define
   _POSIX_SOURCE (and probably must not).

   The problematic C libraries treat _XOPEN_SOURCE the same way.

   likewise.  So now we define bool all the time, unless the macro
   HAVE_BOOL is defined.  If someone is using the Netpbm libraries and
   also another library that defines bool, he can either make the
   other library define/respect HAVE_BOOL or just define HAVE_BOOL in
   the file that includes pm_config.h or with a compiler option.  Note
   that C++ always has bool.
