VS2005 reports the following build failure:
BaseOrderedCollectionRedBlackTreeLib.c(151) : warning C4244:
'return' : conversion from 'int' to 'BOOLEAN', possible loss of data
BaseOrderedCollectionRedBlackTreeLib.c(840) : warning C4244:
'return' : conversion from 'int' to 'BOOLEAN', possible loss of data
This is incorrect. The ISO C standard guarantees that the expressions in
question can only return values 0 and 1, both of which can be represented
by BOOLEAN (== UINT8, == unsigned char).
Silence the incorrect warnings with explicit casts to BOOLEAN.
