[fpc-pascal] rebuild FPC RTL

Fri Jun 12 19:04:44 CEST 2009

RE-make, or re-build?

re-build as in weed out what you dont need. Re-make, yes, I've done 
that.I can't do that on FPOS yet, we have no filesystem.

I execute 'make' on the system unit.

It doesn't catch fpc_short_str_copy and similar right and keeps asking 
for a longInt where a string should be.
similar routines to atoi and itoa from C are in the system unit, but 
they will NOT build as-is.Editing the function calls does not seem to 
help.I am trying to cut down on the number of needed subroutines in the 
system unit, as I don't need everything offered.

I'm working from an idea based on ToroOS' system unit.Lay the files out 
like TP, but with FPC functionality.Much cleaner RTL layout.

I would like to add-in the routines in phases.Strings,heap,those are 
critical.The rest are optional, including syscalls ATM.
I am trying to avoid an int80 if at all possible, as it is written in 
software, not the BIOS.I find int21 and int80 very piss poor 
programming.I have interrupts 0-33 plus IRQ 0-15 already working.It 
would be a waste to say the least to put all those routines in a single 
handler, of which, I can't even find in the Linux kernel sources.
