</H2>

<P>Originally Linux only supported the Minix file system, which cannot
use more than 64Mb per partition.  This limitation is not present in
the more advanced file systems that are now available, such as ext2fs
(the 2nd version of the Extended File System, the `standard' Linux
file system).
<P>If you intend to use ext2fs you can ignore the message.

<H2><A NAME="GCC sometimes uses huge amounts of virtual memory and thrashes."></A> <A NAME="ss11.2">11.2 GCC sometimes uses huge amounts of virtual memory and thrashes.</A>
</H2>

<P>Older versions of GCC had a bug which made them use lots of memory if you
tried to compile a program which had a large static data table in it.
<P>You can either upgrade your version of GCC, or add more swap space if
necessary, or just wait for the program to finish compiling.
