There have been compilers for 32-bit Windows for 20 years which gave
8-byte alignments by default. cygwin changed the default configure
parameter in binutils so as to support alignment about 8 years ago. It
was tolerable to some before then as it matters only for 64-bit and
larger objects (doubles, and SSE, after that was introduced). The
characteristics of the worst compiler (with respect to alignment)
available outside of cygwin don't have a bearing on this list.
If the powers that be have decided that 64-bit mode should be supported
on cygwin setup.exe only by mingw cross compilers, I'll accept that.
