sparc-rtems4.11-gcc error

[Jiri Freyvald]

Luca,
you don't need to compile hello.c from command line, using makefile is 
much easier.
But if you still need it, build some example using makefile,as we all 
suggested, and redirect output to file and you'll probably see all 
parameters for gcc
(for compilation and for linking)
or you can look into $(RTEMS_MAKEFILE_PATH)/Makefile.inc - you'll find 
all parameters there too
