Of course.

This is quite strange. The 2.0.0 netbsd Makefile contains:

$(SYSTEMUNIT)$(PPUEXT) : $(BSDINC)/$(SYSTEMUNIT).pp sysconst.inc  
systypes.inc sy
scalls.inc $(SYSDEPS)
         $(COMPILER) -Us -Sg $(BSDINC)/$(SYSTEMUNIT).pp

I.e., it does specify -Us

At some time, we switched from platform-specific system unit names to  
"system" for all platforms. Afaik that was when switching from 1.x to  
2.x, so normally 1.x should still require sysbsd.

The Makefile contains this:

ifeq ($(findstring 1.0.,$(FPC_VERSION)),)
override FPCOPT+=-dUNIX

So normally it should try to compile sysbsd.pp and not system.pp (rtl/ 
bsd/sysbsd.pp simply includes the contents of rtl/bsd/system.pp, but  
a unit file called "system.pp" cannot have the unit name "sysbsd").  
Is your /usr/local/bin/ppc386 a version 1.0.10 compiler? What does "/ 
usr/local/bin/ppc386 -iV" show? And what does "gmake info" show?  
(when run in the rtl/netbsd directory)

I think the easiest would be to

a) move rtl/netbsd/Makefile and rtl/netbsd/Makefile.fpc aside for  
b) copy rtl/freebsd/Makefile.fpc to rtl/netbsd
c) edit the copied Makefile.fpc, changing all "freebsd" to "netbsd"  
and removing references to gprt0* (that one is only needed for gprof  
support, and is not implemented for netbsd at this time)
d) run "fpcmake" inside the rtl/netbsd directory to regenerate the  
Makefile from the new Makefile.fpc
e) try running gmake again

If you get errors about missing seemingly OS-specific files, check if  
those files exist in rtl/freebsd and either copy/adapt them, or if  
they're not part of a critical unit (like terminfo or so), just  
remove the involved unit from the units to be compiled in the  
Makefile.fpc and regenerate the Makefile.
