(BTW, with --disable-shared you remove the possibility to use any .so
files whatsoever. You can use --enable-static --enable-shared to get
both "all in one binary" and ".so support".)



The following changes since commit 371cea299f0b2eb100b9fc9fb99089640d2d606f:

[Actually there's also the "remove unnecessary cast" patch that is not 
included in this listing, but merging that should be ok.]

commit 0428e5a6541c3f5eaaf683d8da9ea60c44eac4c7
Author: Jan Engelhardt <jengelh@...ozas.de>
Date:   Tue Aug 3 19:58:38 2010 +0200

build: fix static linking

Gabor Z. Papp noted this link-time error when configuring with
--enable-static:

extensions/libext4.a(initext4.o): In function "init_extensions":
extensions/initext4.c:144: undefined reference to "libxt_IDLETIMER_init"
extensions/initext4.c:145: undefined reference to "libxt_TEE_init"

Indeed, since the two modules did not use our special macro "_init"
(which expands to libxt_foo_init), initext4.c could not find them by
that name. Correct this.
