dnl A set of macros to log named variables in the event
dnl of intermediate crash during testing.

dnl macro CCA_DIAGNOSE_INIT([filename])
dnl --------------------------------------------------------------------
dnl Set up the diagnostics file.
dnl The expected lifecycle of the diagnose_ vars is:
dnl unchecked, crashed_in_check, checked.
dnl and if checked, then diagnose_${VAR}_value=/setting
dnl If the configure runs all the way through, then all the
dnl crashed_in_check lines will have been subsequently redefined.
dnl If filename is not given, toolcheck.log is assumed.
dnl Variables of which CCA_DIAGNOSE_INIT is not aware
dnl will have a shorter lifecycle: (undefined, crashed_in_check, check.
