Re: 'make -C specfunc checks' fails on alpha linux with gcc3

[John Ketchum <johnk at qualcomm dot com>]

after you run ./configure, you need to edit the config.status file as follows:

find the line (line 39 in my config.status file) that says:

s%@CFLAGS@%-g -O2%g

and change it to

s%@CFLAGS@%-g%g

then run the config.status file, and proceed as for a normal build

I did this using the gcc 2.96-98 compiler to build gsl-1.0, and it solved 
the problems with failures in the eigen systems routines
