Branch is created for v2.05.

Shortly after that found a showstopper bug:

Konsole output
echo '#include <iostream>' | i586-pc-msdosdjgpp-gcc -c -x c++ -std=c++11 - -o /dev/null

(hint: replace i586-pc-msdosdjgpp-gcc with simple gcc for native build)

Works OK with with -std=c++03, fails with -std=c++11 and -std=c++14

The problem is that our errno.h gets almost completely excluded

PS. following seems to workaround the problem:
