Today I tried two build R-devel_2011-02-06.tar.gz from sources on
FreeBSD 9.0-CURRENT (amd64) with gcc-4.5.2 and I got the following
messages when configuring:
./configure
[..SNIP..]

Until 2.12.1 this works for me. In the NEWS file of 2.13.0 I found in
the INSTALLATION section:
'A C99 compiler is now required, and more C99 language features will be
used in the R sources.'
What exactly characterizes a C99 compiler? Does gcc-4.5.2 belongs to
this? Are the special arguments or knobs to consider? Any other ideas?
Please let me know if more infos are needed.
Thanks in advance for any help,
