>Description:
Test of GSL library (version gsl-1.3) is failed in vector subdirectory with message:

FAIL: gsl_vector_complex_float_swap_elements (static) exchanges elements

To work only with that failed test you can do following:
  cd vector
  rm test_static.o
  make test_static
  ./test_static

Trying to pinpoint the problem I did two things: compiled that library with gcc-3.2.2 in different environment and created small test program. The results are following:
  Testing in different environment:
     1) Linux ema 2.2.18 #1 Wed Jan 24 12:28:55 GMT 2001
        i586 unknown
        with compiler gcc version 3.2.2
        All test went correctly. No failure
     2) CYGWIN_NT-5.0 HOOVER 1.3.17(0.67/3/2) 
        2002-11-27 18:54 i686 unknown 
        with compiler gcc version 3.2.2
        All test went correctly. No failure

  Small test program (named vecfloatcomplexswap.c):
     I cut out relevant test function and put it in
     a test program. It shown no failure


Please be advised that attached tar file contains two files: test_static.i is from distribution testbed which is fails and vecfloatcomplexswap.i is my own test program which works correctly.

-----

If you need more information or want me to do some more tests dont hesitate to contact me. I'd be very happy to help you with resolving this issue.
>How-To-Repeat:
On Sparc machine with Solaris 8 in source directory of gsl-1.3 run
  ./configure --disable-nls
  make
  make check > log 2>&1


Alternatively last command may be replaced with:

  cd vector
  make test_static
  ./test_static > log 2>&1
