./init.sh: line 139: `test-acos': not a valid identifier

[Simon Josefsson]

Below is a strange error that can be seen on:

http://autobuild.josefsson.org/gnulib/log-201002171652277193000.txt

There are no make -j switches here, which I suspected could be involved.

./init.sh: line 139: `test-acos': not a valid identifier
FAIL: test-pread.sh

./init.sh: line 139: `test-acos': not a valid identifier

./init.sh: line 139: `test-acos': not a valid identifier
FAIL: test-xstrtoll.sh

It is just three of the self-tests that fails in this way.

The relevant init.sh line is:

  if test -n "$base_names_"; then
    for base_ in $base_names_; do
      # Create a function named $base whose sole job is to invoke
      # $base_$EXEEXT, assuming its containing dir is already in PATH.
->    eval "$base_() { $base_$EXEEXT"' "$@"; }'
    done
  fi

Could the reason for 'test-acos' showing here be that it is the first
(alphabetically) test?

I'm going to re-run the build to see if it is reproducible, or if the
affected self-tests just happen randomly.
