-C<x> code generation options:
-Cc<x> set default calling convention to <x>
-CD create also dynamic library (not supported)
-Ce Compilation with emulated floating point opcodes
-Cf<x> Select fpu instruction set to use, see fpc -i for
possible values
-Cg Generate PIC code
-Ch<n> <n> bytes heap (between 1023 and 67107840)
-Ci IO-checking
-Cn omit linking stage
-Co check overflow of integer operations
-Cp<x> select instruction set, see fpc -i for possible values
That is it :)
