Yeah, I saw that. I wasn't really expecting the exe to still run after
this or anything, just that it would be something I could get a
reliable fingerprint from. In fact the reason I was doing this is that
I *wanted* to lose information (the date/time field in particular).

Well, I wasn't really expecting it to work, just stabbing in the dark.
However, from the binutils info file "Bug Criteria" section:
]   If you are not sure whether you have found a bug, here are some
] guidelines:
]
]   * If a binary utility gets a fatal signal, for any input whatever,
]     that is a bug.  Reliable utilities never crash.

And from the "Bug Reporting"  section:
]   A number of companies and individuals offer support for GNU
] products.  If you obtained the binary utilities from a support
] organization, we recommend you contact that organization first.

I assumed "support organization"==Cygwin, and thought I'd better be a
good citizen and mention the crash.

Anyway, thanks DaveK for the hint to look at the gcc bootstrap files.
