C Run-Time Warning CRT1001

Error Message

_vcclrit.h is deprecated

The header file _vcclrit.h used to be necessary to avoid loader lock, but is no longer needed and should not be included.

To correct this error

  1. Define the symbol _CRT_VCCLRIT_NO_DEPRECATE before including _vcclrit.h.

  2. Alternatively, remove all unnecessary legacy code that was added according to Converting Projects from Mixed Mode to Pure Intermediate Language.
