# Pascal language mode
#      -Mfpc      free pascal dialect (default)
#      -Mobjfpc   switch some Delphi 2 extensions on
#      -Mdelphi   tries to be Delphi compatible

#      -Mmacpas   tries to be compatible to the macintosh pascal dialects
#
# Turn on Object Pascal extensions by default
#-Mobjfpc

# Assembler reader mode
#      -Rdefault  use default assembler
#      -Ratt      read AT&T style assembler
#      -Rintel    read Intel style assembler
#
# All assembler blocks are AT&T styled by default
#-Ratt

# Semantic checking
#      -S2        same as -Mobjfpc
#      -Sc        supports operators like C (*=,+=,/= and -=)
#      -Sa        include assertion code.
#      -Sd        same as -Mdelphi
#      -Se<x>     compiler stops after the <x> errors (default is 1)
#      -Sg        allow LABEL and GOTO
#      -Sh        Use ansistrings
#      -Si        support C++ styled INLINE

# Allow goto, inline, C-operators, C-vars

# Set the default heapsize to 8Mb
#-Ch8000000

# Set default codegeneration checks (iocheck, overflow, range, stack)
#-Ci
#-Co
#-Cr
#-Ct

# Optimizer switches for i386 compiler
# -Og        generate smaller code
# -OG        generate faster code (default)
# -Or        keep certain variables in registers (still BUGGY!!!)
# -Ou        enable uncertain optimizations (see docs)
# -O1        level 1 optimizations (quick optimizations)
# -O2        level 2 optimizations (-O1 + slower optimizations)
# -O3        level 3 optimizations (same as -O2u)
# -Op        target processor
#     -Op1  set target processor to 386/486
