gcc command line from inside c source

[massimiliano cialdi]

at the beginning of .lst there are some infos like these:

--------------8<------------------
   1 	.file	"at91sam7x.c"

is it possible to access these infos from inside .c source file (maybe
with a predefined macro)?
I need at least "options passed"


thanks
