It only happened last week :)
We already have one portability issue you are probably aware of.
Thanks to testing from Matthias Klose, we've found that the build
fails on armel:

../../../src/solaris/native/sun/nio/fs/UnixNativeDispatcher.c: In
function 'Java_sun_nio_fs_UnixNativeDispatcher_initIDs':
../../../src/solaris/native/sun/nio/fs/UnixNativeDispatcher.c:203:
error: 'fstatat64_wrapper' undeclared (first use in this function)
../../../src/solaris/native/sun/nio/fs/UnixNativeDispatcher.c:203:
error: (Each undeclared identifier is reported only once
../../../src/solaris/native/sun/nio/fs/UnixNativeDispatcher.c:203:
error: for each function it appears in.)
make[6]: *** [/build/buildd/openjdk-6-6b14/openjdk/control/build/linux-arm/tmp/java/java.nio/nio/obj/UnixNativeDispatcher.o]
Error 1

Strangely, it passes on SPARC and PowerPC (both GNU/Linux).  This
function is available in glibc 2.9 so the conditional to just turn it
off for GNU/Linux platforms is wrong.
