small exe size increase from 1.7.0-62 to -63


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:

Obviously 1.5K isn't much of a concern, but is this expected?
