Hardcoded paths is the fact that include and library directories
should be at /usr/local/[lib|include]. In fact I was unable
to compile since I understood that those directory should
be present. That can't be replaced by a "-I" or a "-L" option
from GCC.

For the internal error, I just had to rearange my sources.
Internal errors seems to be caused by a too big C source file.

I'm not calling GCC directly. The Makefile is usefull for that.
But in my makefile I have something like that :

________________________________________________________
CFLAGS=		-O4 -m68000 -I/usr/include
LFLAGS =	-o eureka.prg -L/usr/lib
CC =            /usr/local/bin/gcc

# Make's implicit rules for making a .o file from a .c file...
#
.c.o :
	$(CC) -S $(CFLAGS) $*.c
	$(CC) -c $(CFLAGS) $*.s
	rm -S $*.s

....

eureka:	$(OBJS)
	$(CC) $(LFLAGS) $(OBJS) -lc16 -lm -lgem16 -lldg16

Yes, the new libs are .a instead of .olb and should begin with
lib. Just one thing, how MT_AES16.olb should be renamed taking
account of the 8.3 format ? I'm working with TOSFS !

But what I told you is that the latest ld from binutil 2.9.1
doesn't recognize the "crt0.o". He tells me /usr/lib/crt0.o
file not found, though it exists. I just took the older ld,
renaming the libraries, and all is fine now. Have a look
at http://eureka.atari.org/eurk1199.zip it's correct !
I haven't followed the latest developments of MiNTlib
(no object format are given).

I wish I've been clear enough.

Bye for now ...
