but when I try to compile a Plan 9 C program with pcc it complains
about not being able to find draw.h and friends...

here's the situation, see if you can give me an advice:

	- the png viewer in Plan 9 is broken and has been for a while

	- i can't find the bug (libflate is suspect) so i decide to
	use the default libpng library, which in turn uses the unix
	zlib, both of which are in /sys/src/cmd/gs/

	- i compile both zlib and libpng using pcc.  the pngtest.c
	program that comes with libpng works when compiled with pcc,
	though it never displays anything on the screen (it just
	verifies that it can read png files)

	- i write a very basic 'pngtest' program for Plan 9, which
	uses the same library, however when compiled with 8c it hangs
	on trying to parse all the horrible #if's in png.h, and when
	compiled with pcc it has no understanding of draw()
	commands...

any ideas?
