Hi Martin,
in order to build ROOT on SGI IRIX 6.2 with EGCS (o32 mode) I had to
add a makefile for SGI/EGCS and also to modify Makelib and Make-macros.
As Make-macros is pretty long I include only hints:
- I didn't use libNew.so - the problem with its SGI/EGCS flavour seems to persist
- if you're using EGCS, you may want to link CINT_fakestrm.o and not
CINT_libstrm.o into CINT library.
- i had to add $CILIBS when linking libCint.so:

$(CINTLIB): $(CINTO)
@$(MAKELIB) $(PLATFORM) $(LD) "$(LDFLAGS)" \
"$(SOFLAGS)" libCint.$(SOEXT) $@ "$(CINTO) $(CILIBS)"

However I wouldn't be surprized if on IRIX6.4 you dont' need it.
