*** Error code 1
I know the cause of it and I know the fix. The cause is this:
------------------------------------------------------------------------------- dfr 1999/10/09 05:11:32 PDT
Modified files: lib/libc/alpha/sys Makefile.inc Log: Remove old sig* wrappers.
Revision Changes Path 1.6 +2 -3 src/lib/libc/alpha/sys/Makefile.inc
-------------------------------------------------------------------------------
and the fix is to add sigpending.o and sigsuspend.o to the definition of HIDDEN_SYSCALLS in "src/lib/libc_r/Makefile".
But there was a similar commit for the i386 a few hours later, and I haven't heard any complaints about this breakage on i386 systems. I'm reluctant to commit the fix for the Alpha until I understand why not, because it will affect the i386 too. Can any of you shed some light on this?
I'm pretty sure that this is the right fix. My guess as to why it didn't pop up on i386 is that the old and new implementations were sufficiently close in size that rounding up to 16bytes made them look identical.
