A test with an empty main compiled using gcc-4 under cygwin-1.7.0-63 has a size of 6.5K. After downgrading to 1.7.0-62, without changing anything else, the size goes down to 5.0K. $ cat test.c int main(void) { return 0; } $ gcc test.c -Os -s Looking at objdump differences, both code and data size have gone up: < SizeOfCode 00000800 < SizeOfInitializedData 00001000 --- > SizeOfCode 00000e00 > SizeOfInitializedData 00001600 And we're pulling in a bunch of additional functions from cygwin1.dll and kernel32.dll: > 515c 666 abort > 5170 788 cygwin_create_path > 51b0 812 dll_dllcrt0 > 51d4 1221 memcpy > 51ec 1620 strlen > 51f8 1742 vsnprintf > 5238 336 GetModuleFileNameW > 5274 388 GetStdHandle > 5284 798 VirtualProtect > 5296 801 VirtualQuery > 52a6 827 WriteFile Obviously 1.5K isn't much of a concern, but is this expected?
