In /opt/gcc4*/include/c++/4.*/i686-pc-linux-gnu/bits/ there are * 33.65 MB of stdc++.h.gch/ from gcc-4.1-20071029 * 32.38 MB of stdc++.h.gch/ from gcc-4.2-20071031 * 32.20 MB of stdtr1c++.h.gch/ from gcc-4.2-20071031 * 0 MB of no such dir. stdc++.h.gch/ from gcc-4.3-20071026 O0g.gch and O2g.gch from these dirs eat many MBs of disk space. Why? What is there inside of fat .gch file? What means the .gch file? J.C. Pizarro
