[Ecls-list] Compilation errors using msvc/Makefile

[Claus Brod]

Hi,

I just updated using CVS
(CVSROOT=:pserver:anonymous at ecls.cvs.sourceforge.net:/cvsroot/ecls), and
tried to compile using MS Visual Studio 2008 and msvc/Makefile.

In src/c/main.d, I run into the following error:
../../src/c/main.d(726) : error C2065: 'temp' : undeclared identifier

And indeed, the variable temp is never declared. Fix proposal:

***************
*** 723,729 ****
                value = cl_format(4, Cnil,
make_constant_base_string("~A=~A"), v
ar,
                                  value);
                value = si_copy_to_simple_base_string(value);
!               putenv((char*)temp->base_string.self);
  #endif
        }
        if (ret_val == -1)
--- 723,729 ----
                value = cl_format(4, Cnil,
make_constant_base_string("~A=~A"), v
ar,
                                  value);
                value = si_copy_to_simple_base_string(value);
!               putenv((char*)value->base_string.self);
  #endif
        }
        if (ret_val == -1)


With that fixed, I still run into more problems a little later in
src/c/unixint.d. A couple of those errors occur because Windows knows
SIGSEGV, but not SIGBUS. Those fixes are simple:

        }

        case SIGBUS: {
                ecl_frame_ptr destination = frs_sch(OBJNULL);
                if (destination) {

        default:
                FEerror("Serious signal ~D caught.", 1, MAKE_FIXNUM(sig));
        }

                        printf("SIGSEGV Handler: %x\n", oact.sa_sigaction);

                        sigaction(SIGBUS, NULL, &oact);

                        printf("sigsegv_handler: %x\n", sigsegv_handler);
  #ifdef ECL_USE_MPROTECT
                        printf("Protecting %x\n", the_env);

                                mysignal(code_int, SIG_DFL);
                        else if (code_int == SIGSEGV)
                                mysignal(code_int, sigsegv_handler);
+ #ifdef SIGBUS // {
                        else if (code_int == SIGBUS)
                                mysignal(code_int, sigbus_handler);
+ #endif // }
                        else
                                mysignal(code_int, non_evil_signal_handler);
                        @(return Ct)


With all of the above out of the way, I still run into:
../../src/c/unixint.d(351) : error C2079: 'oact' uses undefined struct
'sigaction'
../../src/c/unixint.d(356) : error C2224: left of '.sa_sigaction' must have
struct/union type
../../src/c/unixint.d(422) : error C2065: 'sigsegv_signal_handler' :
undeclared identifier
../../src/c/unixint.d(436) : error C2065: 'info' : undeclared identifier
../../src/c/unixint.d(436) : error C2223: left of '->si_addr' must point to
struct/union

These occur because the code relies on UNIX-specific signal handling
functionality. I'm not sure how to address those.
