Thanks, that helped,  except for one small case:

make check in cblas/ fails in linking stage:

The compilation flagas were -g -O2.

I recompiled the file test_rotg.c with different flags:
 a) only -g   --  works fine
 b) only -O2  --  works fine


Using nm -u I have got:

Undefined symbols from test_rotg.o:

Have no idea what those LC115, etc. symbols are but it looks again as a compiler
problem.
