Notes
(0002215) bernhardf 03-07-07 09:23	not a buildroot issue but a uclibc one. Assigning accordingly

(0002221) ynglingatal 03-08-07 02:22	I had the same error yesterday with the snapshot of uClibc and gcc 4.1.1 as well as 3.3.5 from buildroot. When changing to uClibc 0.9.28.1 the problem naturally disappears. The problem seems to be that the uClibc-snapshot has two unconditional "extern int _errno; extern int _h_errno;" in libpthread/linuxthreads/pthread.c whereas uClibc 0.9.28.1 uses these under conditional compilation. Since these two variables were never declared properly, without 'extern', in another source file, the error arose.
