[ucLibc/buildroot compile problem]: Conflicting types for posix_fadvise

Hrm.... perhaps one of you more experienced buildroot/uclibc folks can set me
straight. I've been trying [unsuccessfully] to build a nice little embedded
root for myself to deploy in a diskless/fanless little telephony server
project for my home.
I've up until now used "prebuilt" roots like "Freevo" (done for Myth), but I
want more up to date uclibc's and other bits.
My build OS/environment:
Slackware 10.1 based, 2.6.13.4 kernel, gcc-3.3.5, binutils 2.15.92.0.2 20040927.
OK: My attempts thus far have been with:
buildroot-20051023 (snapshot)
buildroot-20051025 (snapshot)
I've tried both gcc-3.4.4 and gcc-3.3.6 compilers selected for the toolchain.
Same result.
I have a dedicated directory, and my config file is as follows (only
non-commented lines included):

Any clues where to even start debugging this build fault? I did some quick
tests with gcc -E to see the preprocessor's output, and it looked like the
right include files were brought in.
Thanks for such a wonderful library/project, guys.
If someone could provide a known flawlessly buildable combination of
kernel/uclibc/etc for i386/pentium-or-pentium3, that would be great, then I
could add on and make changes one at a time until I break it again, etc.
Cheers!
