Still not there, but I may be moving closer. Check out the following

[WINDOZE] E:\pp\source\gtk>set FPCDIR=e:\pp\source

[WINDOZE] E:\pp\source\gtk>make
ppc386.exe -Twin32 -Fue:\pp\source/rtl/win32 -Fue:\pp\source/units/win32 -FE. -di386 glib/glib.pp
Fatal: Can't compile unit SYSWIN32, no sources available make.exe: *** [glib.ppw] Error 1

[WINDOZE] E:\pp\source\gtk>set FPCDIR=e:/pp/source

[WINDOZE] E:\pp\source\gtk>make
ppc386.exe -Twin32 -Fue:/pp/source/rtl/win32 -Fue:/pp/source/units/win32 -FE. -di386 glib/glib.pp
syswin32.pp(25,2) Fatal: Can't open include file systemh.inc make.exe: *** [glib.ppw] Error 1

I think I may be on to something here. Will get back in touch latert in the PM.

Jeff.
