MinGW patches for Insight

- Subject: MinGW patches for Insight
Hi,
I've finally got around to tidying up the patches I use to build Insight
under MinGW which I'd like to submit for your approval. I do have an FSF
assignment on file for gdb, do I need another one for Insight?
should the patches to sim/ppc/table.c, gdb/Makefile.in, gdb/configure.ac
& gdb/configure be submitted to gdb instead?
The timer for the GUI in gdbtk.c should probably be replaced with some
windows equivalent but ifdefing the code suffices for getting Insight
built and running.
When Insight is started under windows it starts up with a console
window, building insight with -mwindows removes this and looks a bit
neater. This is the purpose of the INSIGHT_LDFLAGS I've added to replace
WIN32LDAPP on the insight link commands. I'm not sure if this is the
right thing to do, the cygwin build sets the latter to
"-Wl,--subsystem,console".
The patch to tcl/win/tclWin32Dll.c is basically the one supplied by
Andrew Stubbs in this message to the list -
http://sourceware.org/ml/insight/2005-q3/msg00054.html . I should
probably also mention that I need to set the executable for windows 2000
compatibility to get it to start on my Windows XP Pro box, not yet
tested with Vista.
Here's the complete changelog for the attached patchset generated
against CVS HEAD this morning. I'm not quite sure of the correct format
for this, any feedback gratefully received.
2008-02-07 Dave Murphy <davem@devkitpro.org>
*gdb/Makefile.in
New variable INSIGHT_LDFLAGS, replaces WIN32LDAPP for linking insight
*gdb/configure.ac
New variable INSIGHT_LDFLAGS set to -mwindows under mingw
set tcl configdir to win under mingw32
*gdb/configure
regenerate
*gdb/gdbtk/generic/gdbtk-cmds.c
*gdb/gdbtk/generic/gdbtk-hooks.c
guard <sys/ioctl.h> with HAVE_SYS_IOCTL_H
*gdb/gdbtk/generic/gdbtk-interp.c
include <windows.h> under mingw32
*gdb/gdbtk/generic/gdbtk.c
guard <sys/ioctl.h> with HAVE_SYS_IOCTL_H
(gdbtk_start_timer, gdbtk_stop_timer) remove timer calls under mingw
(gdbtk_init) include windows specific commands under mingw without
cygwin path commands
*gdb/gdbtk/library/download.itb
*gdb/gdbtk/library/interface.tcl
*gdb/gdbtk/library/prefs.tcl
*gdb/gdbtk/library/session.tcl
*gdb/gdbtk/library/srctextwin.itb
check ide_cygwin_path exists before using on windows
*gdb/gdbtk/library/targetselection.itb
(TargetSelection::default_port) default to /dev/com1 under cygwin, COM1
under mingw
(TargetSelection::port_list) use /dev/com under cygwin, COM under mingw
*sim/ppc/table.c
(table_push) correct file read under mingw as well as cygwin
*tcl/win/tclWin32Dll.c
(DllMain, TclpCheckStackSpace) backport EXCEPTION_REGISTRATION code from
TCL mainline
I've tested the resulting Insight builds for powerpc-eabi and arm-eabi
targets, working well so far.
