Fixes bug #63999 (php with fpm fails to build on Solaris 10 or 11).
On second thoughts, while the behaviour _is_ broken, this isn't the right fix. This reverts commit 9b5cb0e.
At present, backslashes have special case handling within fputcsv(): when one is encountered within a field that's being escaped, escaping stops until the next instance of the enclosure character is hit. This can result in malformed CSV. Fixes bug #43225 (fputcsv incorrectly handles cells ending in \ followed by ").
