The tests for macros possibly defined in gthr.h needs to be performed after the corresponding #include. This was tested together with the previous updates to gthr-vxworks-thread.c and gthr-vxworks-cond.c and was meant to be squashed with them. 2010-10-23 Rasmus Villemoes <rv@rasmusvillemoes.dk> libgcc/ * config/gthr-vxworks-thread.c: #include gthr.h before testing the guard defined there. * config/gthr-vxworks-cond.c: Likewise.
