[tlbuild] build failure on x86_64-linux (gcc4.4) since ICU 4.4

[Manuel Pégourié-Gonnard]

Hi,

The current trunk fails to build for me. It used to build just fine, and starts
failing with rev 17641 (icu-4.4). Here are a few informations about my machine:

mpg at roth:~% uname -a
Linux roth 2.6.32-3-amd64 #1 SMP Wed Feb 24 18:07:42 UTC 2010 x86_64 GNU/Linux
mpg at roth:~% gcc --version
gcc (Debian 4.4.2-9) 4.4.3 20100108 (prerelease)

and the error message:

Looks like U_GNUC_UTF16_STRING is defined but char16_t is not recognized as a
type name by my compiler.
