At the type options a type map can be shown.
In the first column of the type map the names of Delphi built-in types and the second column the according names of the C# types are listed. In the further columns some properties of the C# types are given:
Size: size of the type in bytes
Minimum: minimum value of the type
Maximum: maximum value of the type
In System: true, if the type is defined in d2c_system or in System.h, else false.
The last column determines, whether the System namespace is prepended to the according type name in a header.
For example BOOL is a Windows type and therefore has not to be defined in the System namespace. E.g.:
longbool BOOL 4 -2147483648 2147483647 false
Under Linux however BOOL is unknown and could be defined in d2c_systypes.h
longbool BOOL 4 -2147483648 2147483647 true
