| In essence, yes.  The :system-p flag to compile-file, which defaults
| to compiler::*default-system-p*, has two effects on the C output:
| 
| 1) The .data file appended to the .o file is written in verbose
| legible lisp, as opposed to the byte compiled 'fasl' form
| 
| 2) The cmpinclude.h header contents, normally written at the head of
| the .c file, is replaced with #include "cmpinclude.h".  A -I is
| appended to the gcc command to point to the ../h dir relative to the
| current setting of si::*system-directory*, which should point to the
| location of the binary.  There are a few other paths which key off of
| this one, so best to (reset-sys-paths ...) when moving the compiled
| tree or installing.

Thank you very much!
