Re: Branch Version_2_7_0pre

Status update on i386:

1. ./configure had passed

2. gprof was enabled by default again which lead to

Undefined symbols for architecture i386:
  "__mcleanup", referenced from:
      _fSmcleanup in libpre_gcl.a(gprof.o)
      _gprof_cleanup in libpre_gcl.a(gprof.o)
ld: symbol(s) not found for architecture i386

May we ban gprof on macOS completley?

3. Unfortunately system's gcc / ld is too old, so old that it doesn't support -no_pie this can be excluded by patch like this:

anyway, it leads to an error:

4. So, I've decided to ban system's compiler. MacPorts uses clang by default which lead  to an issue:

# ld: illegal text-relocation to ___stack_chk_guard in /usr/lib/libSystem.dylib from _emsg in ...

Somewhere here I feel that ban clang as well right now isn't bad idea :)

5. So, it had compiled suceffuly by GCC-7 which lead to the issue:

which probably the same that I've investigated in different thread.

I've committed some preliminary support for this.  Please note the
register context code is highly non-portable and will take some love to
get right on macosx.  This should be an optional feature.  These macros
support disassembling code at the point of FPE errors.  When all is
ready, you might try

(load (compile-file "../lsp/gcl_fpe_test.lsp"))

Take care,

i386

1. it has missed AC_CHECK_SIZEOF(char,0) in configure.in

2. it has missed FPE_RLST for the case non x86_64, see config.h and 386-macosx.h
