Bug description

Full_Name: Luc Habert
Version: 3.07
OS: solaris 7
Submission from: drakkar.ens.fr (129.199.129.5)

[This is not really a bug report, since the problem seems to be gcc's fault.
I am just posting it here to let others know of the solution I have found.]

On a solaris 7 with a gcc 3.2.1 (it is the only such system I have
available, so that I cannot vouch for the innocence of my sysadmin), the
build of ocaml 3.07 fails during the building of labltk. It happens that at
a time ocamlrun dlopens the previously built dllstr.so', and crashes because that dll lacks a function __eprintf'. This function is defined in
the static libgcc.a, but not in the dynamic libgcc_s.so' that dllstr.so'
depends on. I gather there is a problem in gcc with that respect.

A solution is to force gcc to include the __eprintf' defined in libgcc.a into ocamlrun', which can be achieved by passing a `-Wl,-u,__eprintf' to
the gcc that compiles ocamlrun (and then substituting this ocamlrun to
boot/ocamlrun). Well, I have not deeply tested that str works after that,
but at least it lets the whole distribution compile.
