Seems it was caused by some environment variable (cf. http://stackoverflow.com/questions/12255058/g-4-7-1-compilation-error-conflicting-types-for-strsignal and http://stackoverflow.com/questions/21685255/how-can-i-understand-these-dreadful-errors-when-building-gcc-4-8-2 ) and unsetting them helped.
