Here is a comparison of the output of objdump -h for two compiler versions. The source is src/common/any.cpp from wxWidgets 2.9.1. The GCC compilers were downloaded from mingw.org. GCC 4.5.0 (4.4.0) Total object file size in bytes: 1,080,971 (110,037) Total number of sections: 3,062 (318) Number of: LINK_ONCE_DISCARD .text$xxx sections: 2,887 (145) LINK_ONCE_SAME_SIZE typeinfo .rdata$xxx sections: 128 (128) LINK_ONCE_SAME_SIZE vtable .rdata$xxx sections: 36 (35) .data$xxx sections: 3 (2) Size of: .text: 5,692 (5,308) .data: 0 (0) .bss: 72 (88) .rdata: 2,432 (448) .gcc_except_table: 5,232 (572) .ctors: 4 (4) .eh_frame: 41,996 (2,340) .drectve: 126,440 (5,416) Total size of: LINK_ONCE_DISCARD .text$xxx sections: 132,344 (6,004) LINK_ONCE_SAME_SIZE typeinfo .rdata$xxx sections: 2,552 (2,552) LINK_ONCE_SAME_SIZE vtable .rdata$xxx sections: 1,184 (1,160) .data$xxx sections: 76 (12) Let me know if you need further info. I hope this is helpful. Thanks, Cesar
