I also think that it might be possible to have *COMPILE-IN-CONSTANTS*
automatically default to T where possible eventually.
For the library paths, on ELF systems RPATH can be used (such that the
runtime linker knows where to look for libraries without extra
configuration) and ECL is supposed to automatically link objects with
the required ECL library. Then again I unfortunately don't know for
the equivalent of RPATH for Windows PECOFF here.

To avoid needing a special eclrc when using build scripts, it's also
however possible to use -eval (along with -norc). For instance, in a
GNUmakefile for a project I use the following rule to produce .o
objects before linking them (also note the -s to produce "system"
objects rather than final fasl ones):
%.o: %.lisp
$(ECL) -eval '(progn (setf c::*compile-in-constants* t) (pushnew
:mm-ecl-standalone *features*))' -o $@ -s -compile $<
I suspect that as part of that PROGN, (ext:install-c-compiler) could
also be included... The complete makefile is here, but it was only
tested on unix systems:

Juanjo is better placed than I am to definitely answer and also tests
ECL on Windows, I suspect he'll reply when he's available as well.
