R correct g77 flags for Linux/Alpha (PR#208)
Hello,
I was trying to compile R-base-0.64.1 on Linux/Alpha (RedHat 6.0).
It compiled but it couldn't pass the make check (choked with
tests/Examples/modreg-Ex.R).
I used gdb, and it turned out that the src/library/modreg/src/sinerp.f was
the problem.
else if(j.eq.nk)then
c1 = 0d0
c2 = 0d0
c3 = 0d0
endif> p1ip(1,j) = 0d0- (c1*wjm3(1)+c2*wjm3(2)+c3*wjm3(3))
p1ip(2,j) = 0d0- (c1*wjm3(2)+c2*wjm2(1)+c3*wjm2(2))
I think wjm3(3) should be 0, but it was set to a really tiny value.
So I gave -mieee for g77, and it solved the problem.
The configure correctly identify the CFLAGS for alpha, but -mieee should
be given to g77, too. So in configure.in and configure, you should add
the following (I included a patch below)
By the way, I compiled R on PC164SX + 21164PC/533 using egcs-1.1.2. All
other libraries are Redhat-6.0 default.

To the rpm maintainer: You can simply apply the following patch to the
spec file of R-base-0.64.1-5.src.rpm without patching the configure.in
patch. I also do not know why CFLAGS need to be -O1 instead of -O2??
