bulding libgcc1.a fails for 970917-snapshot ...

[Max Lawson]

	Hi there !

First, I hope you don't find this thread too boring. But my knowledge 
doesn't allow me to build and install egcs ...

The failure I'm facing seems due to the c-preprocessor. Here follows the 
output of a test I made (I've used the flags from the gcc/Makefile to which 
I've added "-v"):

Actually I'm having the same failure as trying to build the following program 

/* -- source z.c-- */
int main()
{
	return 0;
}
/* -- end-source -- */

in the **egcs/gcc/ directory** !
	 ^^^^^^^^^

$gcc -v z.c

I'm not having any problem building this in my $HOME directory !!

What's happening in the egcs-970917/gcc/ directory? What's wrong ?

Going through the list-archive, I can see that people succeed in relishing their eggs for 
pc-linux-gnu systems .. So, please, help me not getting frustrated :-)


Thanx for your time, Max.
