Well it's just a simple invocation of the C preprocessor, so it should be
able to find pkgconf/system.h if it exists in
//E/projects/antilles/Curacao/OS/CelesteRPM/pci-115200_install/include

Perhaps try rerunning "ecosconfig tree", or equivalent in the Config Tool
to regenerate the build tree.

TCL is the chosen scripting language for eCos due to its portability. CDL
is built on TCL. But it hasn't got as far as running the TCL script yet so
that's irrelevant anyway.

Yes, when enabled in the platform MLT configuration, although this hasn't
been done for many platforms yet. Two examples already exist though,
mn10300 and ARM-ebsa285.

If you're interested in how it works, read
services/memalloc/common/current/doc/notes.txt.
