IDC compatibility module
This file contains IDA built-in function declarations and internal bit
definitions. Each byte of the program has 32-bit flags (low 8 bits keep
the byte value). These 32 bits are used in get_full_flags/get_flags functions.
This file is subject to change without any notice.
Future versions of IDA may use other definitions.
