It's even worse than that: if you switch compilers, the declared API in icu-50 headers will not match the ABI of the icu binary. I've just filed https://bugs.gentoo.org/show_bug.cgi?id=440156 after hitting a linking failure when building libreoffice using gcc-4.7 against icu-50 which had been built with gcc-4.6.
