Subject: gcc 3.0.1 fails to compile 8139too.c in 2.4.12ac1
Date: Sat, 13 Oct 2001 07:34:06 -0400 [thread overview]
Message-ID: <20011013073406.A5374@athame.dynamicro.on.ca> (raw)
In linux-2.4.1-ac12, drivers/net/8139too.c makes gcc 3.0.1 fail; gcc 2.95.3
compiles the same code correctly. This, of course, is something the gcc
folks need to address, but I post it here fyi.
# gcc --version
3.0.1
