- Subject: add global warnings flag to hal/common
This is part of the compiler flags update. It adds a new option
CYGBLD_GLOBAL_WARNFLAGS holding all the standard warning-related flags
which then gets incorporated into all the CYGBLD_GLOBAL_CFLAGS default
settings. Note that -Winline has been removed and -Wno-write-strings
has been added.
Doing things this way is only a small step towards sorting out the
compiler flags properly. That involves a great many complications,
probably best left to a future release.
