Where is X.lib?

[Michele31415]

I installed the GfxBase X11R4 X server on my 2000 and would like to write my own X11 programs.  In the readme it says "Restructured a few files in X.lib to reduce the size of xpr by 35k."

This may be a dumb question, but where *is* X.lib?  It's not in the X11 directory and it's not in LIBS:.  find didn't find it either.  I presumably need this if I'm going to compile programs on the Sun using bebbo's cross-compiler.

UPDATE
Apparently, the answer is that it's nowhere.  To get it, you need the "optional programmer's toolkit" (http://web.mit.edu/course/21/21.japan_dev/doc/comp.windows.x_Frequently_Asked_Questions_%28FAQ%29_4_6( which I did not get.  So I'm looking for that now. [time passes...]  Nope - can't find it anywhere.  Does anyone have a copy of this they might let me have?

Yeah, too old now I'm afraid.  The Gfxbase X was apparently highly regarded in its day but without the headers I'm stuck.  So I've moved on to Xami.  At least thatl has headers for it - but no linkable client-side libraries :-(  Fortunately, the README mentions that it's based on Xfree402 source code, by which I assume they mean 4.0.2.  So I found that here: https://repology.org/project/libx11/packages and that's where I am now.  Unless someone has these libraries already that they might be willing to share.

Thanks.  I *think* I found what I need on aminet, but they're sources.  I'm trying to compile that all now with bebbo's great cross-compiler.
