compiling refblas3 with gfortran 4.2

[Kamaraju Kusumanchi]

Hi all

The Debian distribution is trying to migrate from g77 to gfortran 4.2. As
part of this process all the existing packages need to be compiled using
gfortran which were originally compiled with g77.

When trying to compile refblas3 package with gfortran 4.2 instead of g77 on 
a Debian unstable machine, we are encountering some problems. The options
used to compile are

-pipe -O3 -fomit-frame-pointer

$ gfortran -v
Using built-in specs.
Target: i486-linux-gnu
Configured
with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2 --enable-clocale=gnu --enable-libstdcxx-debug --enable-mpfr --enable-targets=all --disable-werror --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu
Thread model: posix
gcc version 4.2.1 20070627 (prerelease) (Debian 4.2-20070627-1)


The compilation seem to go fine. However, When the tests are being run, it
fails as follows


LD_LIBRARY_PATH=$(pwd):$LD_LIBRARY_PATH cblas/testing/xzcblat1 >
debian/test/xzcblat1
awk '/fail/ || /FAIL/ {exit 1}' debian/test/xzcblat1 || (cat

Instead if I do
$ cblas/testing/xzcblat1

That is all the tests are passed. Suggesting that the problem could be in
the libblas.so.3.0 produced by gfortran. Can someone please look into this
problem and offer any suggestions?
