# Split debug information from an executable into a separate file.

# - If debug symbols are stripped before .gnu_debuglink is added,
|
|
# the section will be truncated to .gnu_deb, and hence won't
|
|
# be recognized by gdb.
|
|
# - FIXME: If the above .gnu_debuglink workaround is used, Windows XP
|
|
# and Windows 7 will claim that the executable isn't a valid Win32
|
|
# executable. (Wine ignores it and works fine!)
