I don't remember this being announced here, but anyway, just curious. Did
all copyright owners authorize the license change? Since new one now
requires such notice as you said, and I wouldn't believe the copyright
owners are just a few.

> The MinGW project recently altered the license of their Windows System

> file (EXE or DLL) you create.
> The new license requires you to reproduce its text in every copy or
> substantial portion of the Windows System Libraries that you distribute.
> This means that that even if you just want to distribute a single small
> executable, created with a MinGW-based GCC (like TDM-GCC, or even the
> MinGW official GCC release), you must include a copy of that license.
> Check the license out in the file "COPYING.MinGW.txt", which will be
> installed along with TDM-GCC. Consult with a lawyer if you have any
> concerns about how you use this software.
> Does this new license hurt your usage of GCC? Let the developers know!
