svm seg faults (PR#1901)

[Stefan Böhringer]

Thank you for the hint.
I rebuild gcc and R from scratch and now it works. Here's how on RH7.3,
which might help others:

configured gcc with: --enable-languages=c,c++,objc,f77
--program-suffix=3 --prefix=/usr

in config.site for R the following variables are then set:
CC=gcc3
F77=f773
CXX=g++3
LDFLAGS=-L/usr/lib/gcc-lib/i686-pc-linux-gnu/3.1
-L/usr/lib/gcc-lib/i686-pc-linux-gnu

Thank you very much again.

Best wishes,

	Stefan
