I just assumed (because the code worked a week or so ago) that it probably has something to do with the recent update to gcc, which invalidated my precompiled headers.

ld changed linking behaviour in precise?
Today, my build suddenly had a linker error out of nowhere. Further investigations revealed: The default of the linker flag --as-needed seems to be different compared to lucid and precise a few days ago. While earlier versions assumed --no-as-needed by default, now the default seems to be to use --as-needed. Because of that, some libraries which were needlessly linked against others were not linked anymore. This later caused 'undefined reference' warnings, because said needlessly linked libraries were no longer recursivly included in other libraries. Assuming I diagnosed this correctly, was this change intentional? And for the future: Where can I find the defaults of such command line switches for gcc/ld? Are there any distro specific overrides? Because 'man ld' still tells me that --no-as-needed is the default...
