When trying to build sys-fs/mtools-3.9.10 on autoconf-2.62-r1 and glibc-2.8_p20080602-r0, mtools fails to compile, complaining about Autoconf 'Present But Cannot Be Compiled' warnings and cc1: error: unrecognized command line option "-m486". Not sure if this is an i486 only issue, if so probably something like: if [ "$host_cpu" = i486 ] ; then filter-flags "-m486" fi would fix it, but i have to test that. Reproducible: Always Steps to Reproduce: 1. gcc-config i486-pc-linux-gnu-4.3.1 2. emerge mtools 3.

It's probably time to update CHOST[1]. [1] http://www.gentoo.org/doc/en/change-chost.xml
But that aside, the configure script is apparently doing something awful.
Even when i added: --- mtools-3.9.10/configure.in 2003-02-16 10:13:25.000000000 -0500 +++ mtools-3.9.10/configure-new.in 2008-07-23 11:45:16.000000000 -0400 @@ -330,7 +330,19 @@ AC_CHECK_LIB(socket,main) AC_CHECK_LIB(nsl,main) AC_CHECK_LIB(bsd,main) -AC_CHECK_HEADERS(sys/socket.h arpa/inet.h netdb.h) +AC_CHECK_HEADERS(sys/socket.h arpa/inet.h netdb.h +[if HAVE_SOCKET_H +#include <sys/socket.h> +#endif +] +[[if HAVE_INET_H +#include <arpa/inet.h +#endif +#] +[[if HAVE_NETDB_H +#include <netdb.h> +#endif +]) The warnings still occur, which i think is indicative of a custom config.h. From research version 3.9.11 seems to fix a lot of these issues, probably should just make a version bump request, to make it easy.
works on i486-pc-linux-gnu-4.1.2 and glibc-2.6.1-r0 with: CFLAGS="-O2 -mtune=prescott -pipe -fomit-frame-pointer -g -ggdb" Testing on 4.2.4, but i think it has something to do with '-mtune'.
fixed with 3.9.11 http://sources.gentoo.org/sys-fs/mtools/files/mtools-3.9.11-flags.patch?rev=1.1
