* main.c (print_gdb_version): Update copyright year to 1993. * nm-hp300bsd.h: Decide whether this is BSD 4.3 or 4.4, conditionalize this file on it. FIXME, right way is to split these into two config files. (ATTACH_DETACH): Define for BSD 4.4 (PTRACE_ARG_TYPE): caddr_t for BSD 4.4, unset for 4.3. (U_REGS_OFFSET): Revise for 4.4. (REGISTER_U_ADDR): Separate for 4.4, but it doesn't work yet. * xm-hp300bsd.h: Move definitions of UINT_MAX, INT_MAX, INT_MIN, LONG_MAX into this file to avoid cpp "redefinition" warnings.

In the 2.3.2 release of gcc/g++, how the compiler handles resolving
|
|
multiple inheritance lattices was reworked to properly discover
|
|
ambiguities. We recently found an example which causes this new
|
|
algorithm to fail in a very subtle way. For the time being, this
|
|
patch will make the compiler use the old algorithm, which works for
|
|
the failing case we've found. Note it will revert the compiler's
|
|
ability to properly deduce MI ambiguities in many cases (to its state
|
|
in 2.2.2 and 2.3.1). This bug will be fixed in the next gcc/g++
|
|
release.
