# Do an automated test which involves building and regtesting version
# 1.9 of the GNU Scientific Library (gsl).  This has proven to be a 
# very thorough test of Vex's CPU simulations and has exposed bugs 
# which had not been previously discovered.  Gsl 1.9 contains more
# than 6 million tests as part of its regression suite, and so this
# script's purpose is to runs those tests using valgrind and compare 
# against the same tests run natively.  Note that it produces a
# huge amount of output (about 2 x 620 MByte), so be careful.
# The older gsl16test script produces only about 2 x 7 MByte per run.
# 
# You can download gsl and get more info about it at 
# http://www.gnu.org/software/gsl


# Args:
#     absolute name of gsl-1.9.tar.gz file
#     name of C compiler
#     args for C compiler
#     name of Valgrind
#     args for Valgrind

# Results:  3.7.0   --tool=none
#     x86   1 failure  Ubuntu 10.10
#           FAIL: qawo(f456) elist (7.25063790881233303e-15 observed vs 7.25922435194575979e-15 expected)
#           same failure was also present in 3.6.1
