[R-SIG-Mac] Math bug in Mavericks build

[peter dalgaard]

Dunno if it helps anyone, but a check of local builds lying around shows the issue in

R version 3.0.2 Patched (2013-11-19 r64260) -- "Frisbee Sailing"

but NOT in

R Under development (unstable) (2013-11-11 r64196) -- "Unsuffered Consequences"

So, it seems that either we introduced a change during that period or the build tools changed. Those builds might not be entirely clean, though.

As for C compiler, my current setup has

Peters-iMac:~ pd$ ls -l `which gcc`
-rwxr-xr-x  1 root  wheel  14224 Oct 29 18:10 /usr/bin/gcc
Peters-iMac:~ pd$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.1.0
