-----------
AX_CHECK_FLAG: Fix to work with autoconf 2.59
• AS_VAR_PUSHDEF([FLAGS], [something containing FLAGS]) caused an
infinite loop before v2.65~21.
• AS_VAR_APPEND was new in v2.63b~224.
• AS_VAR_IF was new in v2.63~27.
• AS_ECHO was new in AUTOCONF-2.61a~45, and AC_PROG_GREP in
AUTOCONF-2.59c~744, but their use here is more idiomatically
replaced with a case pattern anyway.
• Before AUTOCONF-2.60b~8, the variable name passed to AC_CACHE_CHECK,
AS_VAR_GET, AS_VAR_SET, and AS_VAR_SET_IF must be left unquoted.
