Make used to only use the search path for nodes that were pure
sources (not targets of other sources). This has been corrected
and now gnu-autoconf generated Makefiles work in directories other
than the source one.
- Suffix transformation rescanning:
Suffix transformations (.c.o:; cc ...) were only recognized in
the past when both suffixes were members of the suffix list.
Thus a sequence like:
.z.b:
echo ${.TARGET}
.SUFFIXES: .z
would cause .z.b: to be inserted as a regular target (and the main
target in this case). Other make programs always add rules that
start with a period in the transformation list and never consider
them as targets. We cannot do that (consider .depend files) so we
resort to scanning the list of the current targets every time a
suffix gets added, and we mutate existing targets that are now
valid transformation rules into transformation rules. If the
transformed target was also the main target, we set the main target
to be the next target in the targets list.
I.e. if you had a line in your Makefile:
../foo.o: foo.c
`..' would be added in the search path. The addition of such paths has
been now disabled. If a pathname contains a slash, then the directory
where such a file is found is not added to the search path. Of course
this eliminates most (all?) use of this function.
alignment of any field in a struct sockaddr is 1, since all members are
chars or char arrays (as noted by Ross Harvey on port-alpha). This causes
the possibility of unaligned access faults when a sockaddr is cast to
e.g. a sockaddr_in. Solution: explicitly direct the compiler to
longword-align the start of a struct sockaddr.
of 8. Since structure padding on the m68k is 16 and on the arm is 32, we
rearrange the frmrinfo portion of the union not to contain a second structure.
This allows the front end to override the default DCR (byte-wide DMA,
x86 byte order, 8-byte FIFO) with different transfer size, byte order, DMA
parameters, and FIFO threshhold. If the loopback select bit is not set for
normal operation, the default is used instead.
Inspired by thoughts from Bernd Ernesti.
