WARNING: you are using gcc version 2.7.2.1 on an Intel x86 processor.
This version of gcc is known to generate incorrect code for the
Objective Caml runtime system on some Intel x86 machines. (The symptom
is a crash of boot/ocamlc when compiling stdlib/pervasives.mli.)
In particular, the version of gcc 2.7.2.1 that comes with
Linux RedHat 4.x / Intel is affected by this problem.
Other Linux distributions might also be affected.
If you are using one of these configurations, you are strongly advised
to use another version of gcc, such as 2.95, which are
known to work well with Objective Caml.
Press <enter> to proceed or <interrupt> to stop.

2.96*) cat <<'EOF'
WARNING: you are using gcc version 2.96 on an Intel x86 processor.
Certain patched versions of gcc 2.96 are known to generate incorrect
code for the Objective Caml runtime system. (The symptom is a segmentation
violation on boot/ocamlc.) Those incorrectly patched versions can be found
in RedHat 7.2 and Mandrake 8.0 and 8.1; other Linux distributions
might also be affected. (See bug #57760 on bugzilla.redhat.com)
Auto-configuration will now select gcc compiler flags that work around
the problem. Still, if you observe segmentation faults while running
ocamlc or ocamlopt, you are advised to try another version of gcc,
such as 2.95.3 or 3.2.
