* Per PR47 add support for buffered test output. This involved adding defines to redirect output to a buffer and dump it when full, at "test pause", and at exit. To avoid problems when redefining exit(), all tests were modified to call rtems_test_exit(). Some tests, notable psxtests, had to be modified to include the standard test macro .h file (pmacros.h or tmacros.h) to enable this support. * cpuuse/task2.c, malloctest/task1.c, putenvtest/init.c, rtmonuse/task1.c, termios/init.c: Modified.
