eCos操作系统源码

	* tests/stdlib/rand4.c:
	Some tidies
	Don't run test when using simplest algorithm

	* tests/signal/signal2.c (main): 
	Don't try to make an FPE on tx39 - its possible to detect but requires
	too much HAL work to be sensible

1999-03-18  Jonathan Larmour  <[e-mail]>

	* src/signal/siginit.cxx (cyg_libc_signals_hwexcept_handler): 
	Use HAL_ENABLE_INTERRUPTS() rather than kernel to enable interrupts

1999-03-18  Mark Galassi  <[e-mail]>

	* tests/PKGconf.mak (TESTS): added rand4 compilation.

	The above changes fix PR 19448

1999-03-17  Jonathan Larmour  <[e-mail]>

	* include/time.h: Add #define of __time_t_defined to placate newlib
