Re: [Mingw-cross-env-list] Congrats - short question.

Boris,

I executed following on a fresh build :

./usr/bin/i686-w64-mingw32.shared-nm 
./usr/i686-w64-mingw32.shared/bin/libstdc++-6.dll > std_shared.txt
./usr/bin/i686-w64-mingw32.shared-nm 
./usr/i686-w64-mingw32.shared/bin/libexiv2-14.dll > exiv_shared.txt
./usr/bin/i686-w64-mingw32.static-nm 
./usr/i686-w64-mingw32.shared/bin/libstdc++-6.dll > std_static.txt
./usr/bin/i686-w64-mingw32.static-nm 
./usr/i686-w64-mingw32.shared/bin/libexiv2-14.dll > exiv_static.txt

Using shared-nm or static-nm didn't make any difference (I'm noob in 
those things,  so maybe that's evident ...).
In attachment you will find a compressed std_shared.txt and exiv_shared.txt.

I'm not sure what those are telling. The symbol is in both, with an 'U' 
in libstdc++ , I don't know if that means something.
Anything else I can do to find the reason ?

Switching (upgrading) compiler I'd like to avoid (unless you are pretty 
sure it is related).
The reason I'm reluctant to upgrade is that this is a program supposed 
to work on Linux and Windows, while my Linux compiler (Ubuntu LTS) is on 
4.8.4.
I don't want to deviate too far from that in order to avoid too many 
differences.

Thanks by the way for your time and effort !

Jos
