Hey all,
The test mass rebuild against r6284 has shown that tcl currently still
fails to build:

This one is caused by the fact that tcl contains its own implementation
of the EXCEPTION_REGISTRATION structure. I've applied a workaround to
the tcl code so that it uses the mingw-w64 implementation of this
structure, but apparently this introduces a new build failure:
i686-w64-mingw32-gcc -c -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions --param=ssp-buffer-size=4 -O2 -fomit-frame-pointer -Wall

-DTCL_CFG_OPTIMIZED=1 -DBUILD_tcl "../tclWin32Dll.c" -o tclWin32Dll.o
../tclWin32Dll.c: In function 'TclWinCPUID':
../tclWin32Dll.c:1170:26: error: 'EXCEPTION_REGISTRATION' has no member
named 'status'
status = registration.status;
^
make: *** [tclWin32Dll.o] Error 1
====
The mingw-w64 header excpt.h has this implementation for the
EXCEPTION_REGISTRATION structure:
typedef struct _EXCEPTION_REGISTRATION {
struct _EXCEPTION_REGISTRATION *prev;
EXCEPTION_DISPOSITION (*handler)(struct _EXCEPTION_RECORD*, void*,
struct _CONTEXT*, void*);
} EXCEPTION_REGISTRATION, *PEXCEPTION_REGISTRATION;
So the mingw-w64 EXCEPTION_REGISTRATION structure currently doesn't have
a field named 'status'.
The tcl of this structure is this:
typedef struct EXCEPTION_REGISTRATION {
struct EXCEPTION_REGISTRATION *link;
EXCEPTION_DISPOSITION (*handler)(
struct _EXCEPTION_RECORD*, void*, struct _CONTEXT*, void*);
void *ebp;
void *esp;
int status;
} EXCEPTION_REGISTRATION;
====
Any ideas on whether this should be fixed in mingw-w64?
Regards,
Erik
