13475	boost_1_66_0, Windows 10, mingw-w4, bootstrap fails - cannot write AppData\Local\Temp file	mhkelley2017@…	Vladimir Prus	"Have successfully built a couple versions of boost (most recently 1_65_1), but was unable to build 1_66_0 using mingw-w64.  ""bootstrap gcc"" returns multiple fatal errors of the form: 

cc1.exe: fatal error: can't open 'C:\Users\Owner\AppData\Local\Temp\ccA01VU9.s' for writing: Permission denied
compilation terminated.

Noted file is actually created somewhere during this, so unclear where/why the failure happens.

I attempted to re-build 1_65_1 (using a couple versions of mingw), with identical results.

Any suggestions where to look?"	Bugs	new	To Be Determined	build	Boost 1.63.0	Showstopper
