[R] bug? nlme 3.1-88 compilation under linx

[Larry Snyder]

>From http://bugs.r-project.org/cgi-bin/R:

   If you are not sure whether you have observed a bug or not, it is a good
   idea to ask on the mailing list R-Help by sending an e-mail to
   r-help at stat.math.ethz.ch rather than submitting a bug report.

I'm wondering whether to submit a bug report on this:

==============================================================
> install.packages("nlme")
   ((several lines removed))
* Installing *source* package 'nlme' ...
** libs
i686-pc-linux-gnu-gcc -I/usr/lib/R/include -I/usr/lib/R/include 
-I/usr/local/include   -fvisibility=hidden -fPIC  -O2 -mcpu=i686 -pipe 
-std=gnu99 -c corStruct.c -o corStruct.o
cc1: error: unrecognized option `-fvisibility=hidden'
make: *** [corStruct.o] Error 1
ERROR: compilation failed for package 'nlme'
==============================================================

Here's my configuration:

> uname -a
> Linux conception.wustl.edu 2.6.12-gentoo-r9 #3 SMP Mon Aug 29 14:00:05 
> CDT 2005 i686 Intel(R) Pentium(R) 4 CPU 2.80GHz GenuineIntel GNU/Linux

This error occurred after I upgraded my gcc to the newest version (it 
also occurred with the previous version):

> gcc-config -c
> i686-pc-linux-gnu-4.2.3

To see if the "-fvisibility=hidden" problem was a bug in gcc, I tried
using it in a toy compilation:

> echo 'main() { }' > in.c
> gcc  -fvisibility=hidden in.c

This returned without an error.

Then I tried:

> i686-pc-linux-gnu-gcc -I/usr/lib/R/include -I/usr/lib/R/include
   -I/usr/local/include   -fvisibility=hidden -fPIC  -O2 -mcpu=i686 -pipe
   -std=gnu99 -c in.c
> `-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.
> in.c:1: warning: return type defaults to 'int'

Conclusion: my gcc seems to accept -fvisibility=hidden.

So: Should I submit a bug report on this?  Thanks -
