[Message part 3 (text/plain, inline)]

Hi,  Dear Maintainers

I met an  issue when try to compile automake with the perl installed in a very long path which larger then max length of shebang ,  here is the reproduce steps

  1.
git clone git <at> github.com:autotools-mirror/automake.git; cd automake
  2.
./bootstrap
  3.
./configure
  4.
make
Failed with error:
...
GEN      doc/aclocal-1.17.1
help2man: can't get `--help' info from bin/aclocal
Try `--no-discard-stderr' if option outputs to stderr
make: *** [Makefile:3818: doc/aclocal-1.17.1] Error 2

The failure is caused by the long path of the perl in aclocal.in,  the shebang  is cutted.  Could we change it like following diff?
diff --git a/bin/aclocal.in b/bin/aclocal.in
index 4d01f3a4d..73d5ee47f 100644

I changed this to a warning. Thanks. -k
