gnucobol-3.1-rc1 and Bashisms in atlocal

Hi Everyone,

This may be causing some problems on OS X. atlocals says around line 85:


But then around line 135:

| if test "$GNUCOBOL_TEST_LOCAL" != "1"; then
|     ABS_COBC="${abs_top_builddir}/cobc/cobc"
|     ABS_COBCRUN="${abs_top_builddir}/bin/cobcrun"
| else
|     ABS_COBC="$(which cobc)"
|     ABS_COBCRUN="$(which cobcrun)"
| fi

I believe $(...) is Bash; atlocal should use backticks for /bin/sh.

atlocal should probably use `command -v cobc 2>/dev/null` for the
test. 'command -v' is Posix and and handles shell aliases properly.
'which' is not posix and does not consult shell configuration files.
