I don't know about VS2005 but in newer versions you can ignore specific link warnings by adding /ignore:4099

It cannot be disabled, as it is on Microsoft's list of unignorable warnings.

If you have the source for the libraries you are using, you can rebuild them in Debug mode and copy the generated *.pdb files to the same directory as the libs you are linking.

If you do not have the source, there is a workaround, but it involves hex-editing the linker: https://connect.microsoft.com/VisualStudio/feedback/details/176188/can-not-disable-warning-lnk4099

Essentially, hex edit your link.exe (after backing it up!) to zap the occurrence of 4099 in the list of non-ignorable warnings. I did it and the hundred or so 4099 warnings disappeared! [L]ook for the hex bytes 03 10 00 00 (which is 4099 as a 32-bit little-endian hex value). Change it to (say) FF FF 00 00, save the file and you're done.
