Hi Joel,

I figure it's something different about my build environment.
That doesn't seem to be the problem:

  $ tar tvf bison-2.4.593-a78a.tar.gz|grep parse-gram
  -rw-r--r-- 0/0    21804 2011-03-17 18:00 bison-2.4.593-a78a/src/parse-gram.y
  -rw-r--r-- 0/0   103025 2011-04-18 21:59 bison-2.4.593-a78a/src/parse-gram.c
  -rw-r--r-- 0/0     5845 2011-04-18 21:59 bison-2.4.593-a78a/src/parse-gram.h

I can reproduce it by running "make dist", unpacking the result
and then using it to perform a non-srcdir build.

  tar xf bison-2.4.593-a78a.tar.bz2
  cd bison-2.4.593-a78a
  mkdir .j && cd .j && ../configure && make
  ...

/bin/sh ../build-aux/ylwrap ../src/parse-gram.y y.tab.c src/parse-gram.c 
y.tab.h src/parse-gram.h y.output src/parse-gram.output -- tests/bison -y -dv 
--warnings=all,error --report=all
/bin/sh ../build-aux/ylwrap ../src/scan-code.l lex.yy.c src/scan-code.c -- flex
/bin/sh ../build-aux/ylwrap ../src/scan-gram.l lex.yy.c src/scan-gram.c -- flex
/bin/sh ../build-aux/ylwrap ../src/scan-skel.l lex.yy.c src/scan-skel.c -- flex

[Exit 2]

FYI, I've just  bootstrapped bison from scratch, but without using
e.g., personally-installed automake build from automake.git's master.
That solved the problem, but I don't know precisely why yet.
I'll investigate, eventually.
