-  /* Acorn's RISC-iX has a wacky way of initialising the position of the heap.
-   * There is a little table in crt0.o that is filled at link time with
-   * the min and current brk positions, among other things.  When start
-   * runs, it copies the table to where these parameters live during
-   * execution.  This data is in text space, so it cannot be modified here
-   * before saving the executable, so the data is written manually.  In
-   * addition, the table does not have a label, and the nearest accessible
-   * label (mcount) is not prefixed with a '_', thus making it inaccessible
-   * from within C programs.  To overcome this, emacs's executable is passed
-   * through the command 'nm %s | fgrep mcount' into a pipe, and the
-   * resultant output is then used to find the address of 'mcount'.  As far as
-   * is possible to determine, in RISC-iX releases prior to 1.2, the negative
-   * offset of the table from mcount is 0x2c, whereas from 1.2 onwards it is
-   * 0x30.  bss_end has been rounded up to page boundary.  This solution is
-   * based on suggestions made by Kevin Welton and Steve Hunt of Acorn, and
-   * avoids the need for a custom version of crt0.o for emacs which has its
-   * table in data space.
