  83    * The text address, offset, and size of ZMAGIC files depend
  84      on the entry point of the file:
  85      * entry point below TEXT_START_ADDR:
  86        (hack for SunOS shared libraries)
  87        start at 0, offset is 0, size as stated.
  88      * If N_HEADER_IN_TEXT(x) is true (which defaults to being the
  89        case when the entry point is EXEC_BYTES_SIZE or further into a page):
  90        no padding is needed; text can start after exec header.  Sun
  91        considers the text segment of such files to include the exec header;
  92        for BFD's purposes, we don't, which makes more work for us.
  93        start at TEXT_START_ADDR + EXEC_BYTES_SIZE, offset is EXEC_BYTES_SIZE,
  94        size as stated minus EXEC_BYTES_SIZE.
  95      * If N_HEADER_IN_TEXT(x) is false (which defaults to being the case when
  96        the entry point is less than EXEC_BYTES_SIZE into a page (e.g. page
  97        aligned)): (padding is needed so that text can start at a page boundary)
  98        start at TEXT_START_ADDR, offset PAGE_SIZE, size as stated.
  99
 100     Specific configurations may want to hardwire N_HEADER_IN_TEXT,
 101     for efficiency or to allow people to play games with the entry point.
 102     In that case, you would #define N_HEADER_IN_TEXT(x) as 1 for sunos,
 103     and as 0 for most other hosts (Sony News, Vax Ultrix, etc).
 104     (Do this in the appropriate bfd target file.)
 105     (The default is a heuristic that will break if people try changing
 106     the entry point, perhaps with the ld -e flag.)
