dnl PAC_RUN_LOG mimics _AC_RUN_LOG which is autoconf internal routine.
dnl We also make sure PAC_RUN_LOG can be used in AS_IF, so the last
dnl test command should have terminating ]), i.e. without newline before ]).

{ AS_ECHO(["$as_me:$LINENO: $1"]) >&AS_MESSAGE_LOG_FD

dnl PAC_COMMAND_IFELSE is written to replace AC_TRY_EVAL with added logging
dnl to config.log, i.e. AC_TRY_EVAL does not log anything to config.log.
dnl If autoconf provides AC_COMMAND_IFELSE or AC_EVAL_IFELSE,
dnl AC_COMMAND_IFELSE dnl should be replaced by the official autoconf macros.
