scalc UNO api compilation question about header files

[Neeraj Rai]

I think I get it now. I didn't realize earlier and I had to generate
headers for system UNO types.
The sample Makefile - it seems - was assuming they were generated, so -T
was specified
to generate the new ones.
Once I removed the -T to generate all, both the
headers XEnumerationAccess/XDesktop
were generated.
Also, the sample Makefile I was using, didn't not specify -O so the output
was going to current dir. The next steps were including -I. to pick it up.
This is not ideal, but for now, it helps me understand.
When I have more than 1 project, the system UNO types can all go in common
dir and generated once. And this perhaps what stdtarget.mk is trying to
acheive via SDKTYPEFLAG.
One last question - can I generate the system UNO types once per box, may
be after SDK installation?

thanks
Neeraj
