Re: gfortran vs g77

Dear Fons,

I updated my linux distro, which is a Gentoo Linux on i686 cpu (Intel T7400) with gcc version 4.1.1 (Gentoo 4.1.1-r3) and gfortran version 4.1.1.

I recompiled the blas, lapack and cernlib libraries (2005) with gfortran.

In order to be able to compile root (head version 5.15/01) I added the following fortran libraries to Makefile.linux:

F77LIBS = -lgfortran -lgfortranbegin -lnsl

instead of
F77LIBS = -lnsl

Without them I obtain a lot of unresolved symbols of gfortran libraries and the compilation fails.

Cheers,
Stefano
