[bug-gettext] preceding keywords substitution fail for woe platform

[Roumen Petrov]

Hello

After some modification to build and test process finally I get language 
dependent output for lang-c test. The test fail as preceding keywords 
are not substituted :
==================
.....
< 2 morceaux de gateau
< EUR remplace FF.
---
.....
> 2 morceaux de gateau
> %2$s remplace %1$s.
==================
