[ccache] "unsupported compiler option" - more information

[Karsten Burger]

Hello,

we have quite many compiler misses and at the same time a high number of "unsupported compiler option" reported, does anybody know what this means, which options are unsupported,  and whether this could be changed?  Is the counter incremented only once per file, or is it incremented perhaps several times per file if several options are unsupported?

Also, is there a more detailed documentation somewhere (more than the man-page)?

I would also appreciate a search option for the mailing lists.

Thanks a lot, 

Karsten
