+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 2.7.2 or 2.7.2.2, which are
+known to work well with Objective Caml.
+
+Press <enter> to proceed or <interrupt> to stop.
