120b82d368 Don't look for headers outside of the source or object directories. In 
particular, don't use DESTDIR. Such creates an unnecessary dependency
on the build machine.

a054c02d31 grep: change some int types. 
Change several int variables to size_t, ssize_t, or ptrdiff_t.
This should fix the bug described in CVE-2012-5667 when an input
line is so long that its length cannot be stored in an int
variable.

This is based on NetBSD's revision which says:

This change to NetBSD's version of GNU grep 2.5.1 (licenced under
GPLv2) was made without direct reference to any code licenced
under GPLv3.

0b7fec6762 Build and install a BSD licensed grep. 
If WITH_BSD_GREP is not set, it will be 'bsdgrep' and GNUgrep will be
'[ef]grep'.  Otherwise, BSD-grep will be the grep family, and GNUgrep
will be 'gnugrep'.

6eaf14ce79 For files not named on the command line, only the basename is compared 
to the exclude pattern.
Change this so that "grep --exclude='*/.svn/*' -[Rr] foo *" DWIM.
