Thanks for the reply Sergei. As far as I understand you are going to revert
hal_intr.h to state before Attachment 1092 and in addition shift
CYGNUM_HAL_INTERRUPT_RTC definition after inclusion of var_intr.h. Am I right?
It would fit, since var_intr.h shall be included after definition of Cortex-M
system vectors and before CYGNUM_HAL_INTERRUPT_RTC.
