put + after a boolean switch option to enable it, - to disable it
-a the compiler doesn't delete the generated assembler file
-al list sourcecode lines in assembler file
-ar list register allocation/release info in assembler file
-at list temp allocation/release info in assembler file
-b generate browser info
-bl generate local symbol info
-B build all modules
-C<x> code generation options:
-CD create also dynamic library (not supported)
-Ch<n> <n> bytes heap (between 1023 and 67107840)
-Ci IO-checking
-Cn omit linking stage
-Co check overflow of integer operations
-Cr range checking
-CR verify object method call validity

*** press enter ***
-d<x> defines the symbol <x>
-e<x> set path to executable
-E same as -Cn
-F<x> set file names and paths:
-FD<x> sets the directory where to search for compiler utilities
-Fe<x> redirect error output to <x>
-FE<x> set exe/unit output path to <x>
-Fi<x> adds <x> to include path
-Fl<x> adds <x> to library path
-FL<x> uses <x> as dynamic linker
-Fo<x> adds <x> to object path
-Fr<x> load error message file <x>
-Fu<x> adds <x> to unit path
-FU<x> set unit output path to <x>, overrides -FE
-g generate debugger information:
-gg use gsym
-gd use dbx
-gh use heap trace unit (for memory leak debugging)

-i information
-iD return compiler date
-iV return compiler version
*** press enter ***
-iSO return compiler OS
-iSP return compiler processor
-iTO return target OS
-iTP return target processor
-I<x> adds <x> to include path
-k<x> Pass <x> to the linker
-l write logo
-n don't read the default config file
-o<x> change the name of the executable produced to <x>
-pg generate profile code for gprof (defines FPC_PROFILE)
-P use pipes instead of creating temporary assembler files
-S<x> syntax options:
-S2 switch some Delphi 2 extensions on
-Sc supports operators like C (*=,+=,/= and -=)
-sa include assertion code.

-sh Generate script to link on host
-u<x> undefines the symbol <x>
-U unit options:
-Un don't check the unit name
-Ur generate release unit files
-Us compile a system unit
-v<x> Be verbose. <x> is a combination of the following letters:
e : Show errors (default) d : Show debug info
w : Show warnings u : Show unit info
n : Show notes t : Show tried/used files
h : Show hints m : Show defined macros
i : Show general info p : Show compiled procedures
l : Show linenumbers c : Show conditionals
a : Show everything 0 : Show nothing (except errors)
b : Show all procedure r : Rhide/GCC compatibility mode
declarations if an error x : Executable info (Win32 only)
occurs
-V write fpcdebug.txt file with lots of debugging info
