Hi,
indeed... it is very strange..
http://hackage.haskell.org/trac/ghc/ticket/3791
is detailed and it even worked. I have seen several similar posts...
however according to
http://gcc.gnu.org/onlinedocs/gcc-3.2.3/gcc/Option-Summary.html#Option%20Summary
neither in it or in the 4.4/4.5 series I can find this option. The
closest is no-relax-immediate but not for sparc. What is this, black
magic? The quest for the hidden undocumented GCC option?

The alternative is to add a configure check. In configure.ac, we need to try
determining if the compiler supports -mno-relax. With gcc is not that
difficult,
as we'd presumably simply grep the output of "gcc --target-help". But clang
doesn't seem to recognize --target-help. How do you get the list of
command-line
compiler options for clang ?
To print all of the compiler options, you can do clang -cc1 -help, although
that may not be what you want. I can't find -mno-relax documented in GCC, so
I'm not sure what it actually does...
