hdf5/bin/errors
David Young 7c82abc3ff Not every system has perl installed in /usr/bin/, so change the shebang
(#!) line to `/usr/bin/env perl` to locate perl on the PATH.

Everything after the first pathname in the shebang line is treated as
a single argument to the command interpreter (/usr/bin/env "perl -w"),
and there is not ordinarily any such program as "perl -w".  So if the
old shebang line used an option such as `-w`, add a `use warnings;`
statement to the script---note that the semantics change slightly.
`bin/destdep` uses a trick to pass `-p` to `/usr/bin/env perl`.  It
couldn't hurt to use the same trick to pass `-w`.

With these changes, `sh autogen.sh` runs on NetBSD.  It ought to still
work on every other system HDF5 supports, too.

# Purpose: This script will read standard input which should be a
# function prologue followed by a C function and will emit
# on standard output the same source code with the function
# prologue containing documentation for the various errors
# that occur in the function.
#
# Errors are raised by calling HGOTO_ERROR() or
# HRETURN_ERROR(). The reason for the error message is a
# comment which appears immediately after the error macro
# call and is contained entirely on one line:
#
# HRETURN_ERROR (...); /*entry not found*/
#
# If such a comment doesn't exist, then the previous comment
# is used, subject to the constraint that raising an error
# clears the previous comment.
#
# /* Entry not found */
# HGOTO_ERROR (...);
#
# Emacs users can use this script interactively with the
# c-mark-function and shell-command-on-region functions which
# are normally bound to M-C-h and M-|.
# Split STDIN into the prolog and the function body. Preserve leading
