Thanks, very helpful. The problem seems to be that your installed
gcc is out of sync with your processor. The configure test for
SSE2 intrinsics is passing OK and gcc is happily allowing you to
compile with the -msse2 flag, but in fact the cpu has no sse2
support, so naturally the gretl binary is going to issue illegal
instructions.
I suppose (hope) this case is quite rare, in which case it can be
handled by --disable-sse2, but maybe we can put a more thorough
test for sse2 into the configure script.
