/* Windows/DOS/DOSX Version
* ------------------------
* There are two main issues: hosting the compiler on windows,
* and generating (targetting) windows/dos/dosx executables.
* The "_WIN32" and "__DMC__" macros control hosting issues
* for operating system and compiler dependencies, respectively.
* To target linux executables, use OMFOBJ for things specific to the
* OMF object file format, and TARGET_WINDOS for things specific to
* the windows/dos/dosx memory model.
* If this is all done right, one could generate a win/dos/dosx object file
* even when compiling on linux, and vice versa.
* The compiler source code currently uses these macros very inconsistently
* with these goals, and should be fixed.
*/
/* Linux Version
* -------------
* There are two main issues: hosting the compiler on linux,
* and generating (targetting) linux executables.
* The "linux" and "__GNUC__" macros control hosting issues
* for operating system and compiler dependencies, respectively.
* To target linux executables, use ELFOBJ for things specific to the
* ELF object file format, and TARGET_LINUX for things specific to
* the linux memory model.
* If this is all done right, one could generate a linux object file
* even when compiling on win32, and vice versa.
* The compiler source code currently uses these macros very inconsistently
* with these goals, and should be fixed.
*/
/* OSX Version
* -------------
* There are two main issues: hosting the compiler on OSX,
* and generating (targetting) OSX executables.
* The "__APPLE__" and "__GNUC__" macros control hosting issues
* for operating system and compiler dependencies, respectively.
* To target OSX executables, use MACHOBJ for things specific to the
* MACH-O object file format, and TARGET_OSX for things specific to
* the OSX memory model.
* If this is all done right, one could generate an OSX object file
* even when compiling on win32, and vice versa.
* The compiler source code currently uses these macros very inconsistently
* with these goals, and should be fixed.

* To target FreeBSD executables, use ELFOBJ for things specific to the
