Re: passing -o filename with multiple compile

[Juan Casero <casero at bellsouth dot net>]

Thank you very much for your help Roderich.  Following your instructions below I
was able to begin compiling the X server with egcs-1.1 and so far I have not
encountered any problems.  If I find something strange I will post it on the
egcs list.

Thanks.
