[Bug other/17444] New: lots of gcov failures with --enable-mapped-location

["bothner at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I get lots of new failures in gcc.misc-tests/gcov.exp
if I configure with --enable-mapped-location.

Running /home/bothner/GNU/gcc.head/gcc/testsuite/gcc.misc-tests/gcov.exp ...
FAIL: 14:is -:should be 11
FAIL: 15:is -:should be 10

... etc ...

Could someone please look into this?  Possibily related is
that profile.c failed to compile.  I'll attach my patch for
the latter, which may well be wrong.
