[Bug c/24976] New: simple hexadecimal number parsed as C99 hex float

["bernie at develer dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This testcase:

  int a = 0xe+100;

Produces a diagnostic message that would surprise
most users:

 foo.c:1:9: error: invalid suffix "+100" on integer constant


I'm not sure what the standard says about ambiguity
between the hex float notation and the regular + operator,
but many users are going to think of this behavior as
a parser bug.
