Yeah, I know, but then again: even the "-Wl,-Bstatic" flag is not
portable, because the IRIX linker needs "-Wl,-B,static" (note the extra
",").

The "-Bstatic" and "-Bdynamic" flags tell the linker to link the next
librarieS (not the next librarY) following the switch static/dynamic. In
that way you can actually choose which libraries you want static, and
which dynamic. For example:

  gcc -o foo foo.o -Wl,-Bstatic  -L/usr/X11R6/lib -lgtk -lgdk -rdynamic \
    -lgmodule -lglib -Wl,-Bdynamic -ldl -lXext -lX11 -lm

links the GTK+ libs static, but the dynamic link, X11, and math libraries
dynamic.
