Ebuild media-libs/libfprint-0.0.6 from the wschlich-testing overlay, will not compile as it requires the -fgnu89-inline gcc flag. To my knowledge this is only avalable in gcc 4.1.3 but current stable version is 4.1.2. Reproducible: Always

Did you managed to get it working ? I have exactly the same problem....
The simplest fix would be to upgrade gcc to >=4.1.3, but these are all still unstable. I have not tested this though as using a unstable gcc could lead to a lot of problems. Alternatively if a check could be added to the configure for whether -fgnu89-inline option is available would be ideal.
Slightly offtopic: While the sources from sourceforge are fine, those portage downloaded from http://mirror.pacific.net.au were corrupt (filesize mismatch). I get the same issue (-fgnu89-inline) here on amd64 with gcc-4.1.2.
I have upgraded to gcc-4.3.1-r1 for other reasons and this does indeed build fine.
Seems that it's forced by configure: configure:AM_CFLAGS="-std=gnu99 -fgnu89-inline -Wall -Wundef -Wunused -Wstrict-prototypes -Werror-implicit-function-declaration -Wno-pointer-sign -Wshadow" configure.ac:AM_CFLAGS="-std=gnu99 -fgnu89-inline -Wall -Wundef -Wunused -Wstrict-prototypes -Werror-implicit-function-declaration -Wno-pointer-sign -Wshadow"
gcc-4.3 will go to stable "soon", then, this will be hopefully fixed. Only one question, I mailed to thinkfinger upstream and he told me that libfprint should replace thinkfinger then, why is libfprint still in a separate overlay and not in "official" tree? Thanks :-)
Since gcc-4.3 has been out for a while now, I'm marking this as fixed.
