secure_getenv: port better to FreeBSD and Solaris * lib/secure_getenv.c [!HAVE___SECURE_GETENV]: Include unistd.h if HAVE_ISSETUGID, otherwise define a dummy issetugid. (secure_getenv) [!HAVE___SECURE_GETENV]: Use getenv if not issetugid. This works better on BSDish platforms. * m4/secure_getenv.m4 (gl_PREREQ_SECURE_GETENV): Test for issetugid if __secure_getenv is missing.
