Details:

When compiling with gcc 2.95.4 on FreeBSD 4.11-STABLE, this error came
about:



gmake[2]: Entering directory `/usr/home/adkatz/grep-2.6.3/src'
  CC       dfa.o
dfa.c: In function `dfaexec':
dfa.c:2802: syntax error before `unsigned'
dfa.c:2803: `saved_end' undeclared (first use in this function)
dfa.c:2803: (Each undeclared identifier is reported only once
dfa.c:2803: for each function it appears in.)
gmake[2]: *** [dfa.o] Error 1
gmake[2]: Leaving directory `/usr/home/adkatz/grep-2.6.3/src'
gmake[1]: *** [all-recursive] Error 1
gmake[1]: Leaving directory `/usr/home/adkatz/grep-2.6.3'
gmake: *** [all] Error 2


This appears to be due to declaration of a variable later in a function than
it should be.  I moved the declaration and things seem fully funcitonal, but I
haven't bothered to figure out how to thoroughly test that specific function.

Patch attached.

moved declaration of saved_end to top of function, kept assignment in-place.
