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 2.7.2.3 or 2.95, which are
known to work well with Objective Caml.
Press <enter> to proceed or <interrupt> to stop.
