Soo, which kernel (and which _version_) are you seeing this ?
These particular messages were produced while compiling (~)gentoo-sources-2.6.22-r4 (running (~)gentoo-sources-2.6.22-r3). But I definitely already observed them while compiling r3; and I think also for r2, which was the first version of 2.6.22 I tried on this box.
Can you please test this with the latest development kernel, 2.6.23-rc6 as of this writing? Please also post your kernel .config.

Created attachment 131257 [details] stdout and stderr of ``make'' for gentoo-sources-2.6.22-r6 This still shows the suspicious ``Section mismatch'' warnings concerning swsusp.
The latest development kernel is: sys-kernel/vanilla-sources-2.6.23_rc6. Can you test with that one please?
Created attachment 131259 [details] vanilla-sources-2.6.23_rc6.make.log With vanilla-sources-2.6.23-rc6, far fewer ``Section mismatch'' messages, but still quite a few deprecated and warn_unused_result messages.

These shouldn't really cause any problems: they are warnings, not errors. If there is actually something wrong with your system, please open a bug about that.
