[ccache] A problem with headers (probably)

Hi all,

i use ccache on Gentoo Linux and have a problem with a specific package.
When compiling it without ccache it works fine. When ccache is activated
the compile fails with an
error: nauty.h: No such file or directory
I attached part of the build log.

If i clear the cache, the first compile runs flawlessly, then if i
change some compiler options (i.e. -O3 instead of -O2) and compile again
the compile fails. Maybe there are some false positive hits ??

Is there anything nasty the makers of a program could do to trigger such
a problem?

Any hint is appreciated
Thomas
