  Eliminate non-ANSI C compatibility macros
  
  libjpeg-turbo has never supported non-ANSI C compilers.  Per the spec,
  ANSI C compilers must have locale.h, stddef.h, stdlib.h, memset(),
  memcpy(), unsigned char, and unsigned short.  They must also handle
  undefined structures.

   * The actual configuration options for a particular installation are stored
   * in jconfig.h.  On many machines, jconfig.h can be generated automatically
   * or copied from one of the "canned" jconfig files that we supply.  But if
   * you need to generate a jconfig.h file by hand, this file tells you how.
