Bug description

Full_Name: John Harrison
Version: Caml Light 0.75
OS: Windows XP + Cygwin
Submission from: jffwpr01.jf.intel.com (134.134.136.1)

Has anyone built Caml Light under Cygwin? OCaml compiles without problems but I
have severe problems with Caml Light 0.75. This is the latest Cygwin under
Windows
XP.

0. A relatively minor first problem in "src/runtime", a type inconsistency
   between "sys_errlist" in sys.c and standard header errno.h. But it was only the
   addition of "const" qualifiers so I modified sys.c accordingly.

1. After building inside "src/runtime", the subsequent copy of "camlrun" fails:

cp: runtime/camlrun' and ./camlrun' are the same file

This may be something to do with Cygwin's weird phantom "exe" extensions.
Anyway
I just copied runtime/camlrun.exe to camlrun instead, and dealt with an
identical
problem in the following "yacc" build in the same way.

2. Stranger still, the build inside "lib" fails early:

../camlrun ../camlcomp -stdlib . -O none -g -W arg.mli
Fatal error: the file ../camlcomp is not a bytecode executable file

As far as I can see from the source, this means an unexpected magic number, but
the file (according to "od") does end with "CL07" as expected. I didn't delve
deeper. Any suggestions?

John.
