Bug in libiberty strtod.c

[Stuart Griffith]

Just a note to let you know that the source for strtod that has been
distributed as part of libiberty for the Cygnus 99r1 and 00r1 releases
contains an error. In the code that checks for an input string of "inf"
or "infinity" when "infinity" is found the pointer into the string is
advanced by 7. This should be 8. (In the copy of the sources I have this
is line 62.)
