The __thumb2__ part is a red herring; configure proceeds past it just 
fine.  The issue is

at workdir/UnpackedTarball/nss/nspr/configure.in:1931.  For me, it 
determines CC_VERSION=19.16.27024.1.  For you, the sed invocation 
apparently fails, leading to an empty CC_VERSION, presumably because 
your French MSVC outputs something that the code can't cope with.

In the cygwin shell where you do `make`, do the following:

> $ grep CC= config_host.mk
to get the CC=... line, should be something like CC=C:/PROGRA...  Do the 
below two commands, with each XXX replaced by the exact value from that 
CC= line:

> $ XXX -v

and

> $ XXX -v 2>&1 | sed -ne 's|.* \([0-9]\+\.[0-9]\+\.[0-9]\+\(\.[0-9]\+\)\?\).*|\1|p'

and provide the output of each.
