cbf6d06de2 Bug removed: the trailing zero at the end of a growstring was not 
explicitly written in doassign(trans.c).
Only luck kept the program together.

8f7669b247 1 - A few minor syntactic changes. 
2 - Altered the description of strings as initializers. (sequence of U1's).

e29ef2395a Compile-time option GLOBAL_OPT defined. If set, the resulting 
peephole optimizer will be suitable for optimizing the output of
the global optimizer. In particular, it doesn't change the register
messages.

546bcee023 1 - The prop keyword with is flags is now obsolete. Its function is 
taken over by several other keywords: stdin, stdout, prep, optimizer,
    combiner and linker.
2 - The search order is changed. First {EM}/lib/{M}/descr, then
    {EM}/lib/ack/{M}, finally {M}.

a9beb24998 The t_do bits are not set by this module. The t_next entry is used 
to see whether the scan for this phase is already done.
t_do is now set in add_inputs(files.c).

96da898a4a 1 - The t_do flags is now set by add_inputs(files.c). 
2 - Recognize the fact that it is possible to start a combiner without
    input files.
3 - Removed -d flag. Overflow for -v (>2) now ends up in debug.
    -v may be followed by a number indicating the increment.

a69b503ad0 1 - The outfile entry is only used when the output file must not be thrown 
away.
2 - If a combiner has no named input file (only libs+flags) then issue
    a warning message and make up a name.

5fd55904ec pem did not generate a register message for var-parameters of 
array- or record type. The routine "treewalk" is modified.
It generates a register message for every var-parameter, even
if it has its noreg-flag set.

c08fe56b97 Combiners (ego, linkers) now use a list of path's(ack.h) to indicate 
their input files.
Unmatched flags are now sent to the linker.

ed3db93f56 1 - A transformation is succesfull when 
a - a stopsuffix is indicated and met,
    b - the last transformation is included in the transformation path.
2 - Maintains a 'cash' of best paths for all transformation to be executed.

cfdc2ce05f 1 - added keywords callname and outfile. See manual. 
2 - multiple combiners are allowed now.
3 - A different search mechanism is used for finding descriptor files.

845c92825a 1 - callname recognition is moved to rmach.c. 
2 - The overall scheme is altered.
	first, all input files are processed until a combining phase is met.
	then, all the combining phases are executed, the resulting files
	are again processed until a combiner (or final) phase is met.
3 - The EM_DIR shell variable can be used to set ack's idea of the EM
    home directory.

3adba1b759 1 - The names of temporary files are now Ack'hex''unique'.'suffix'. 
'hex' is the pid of the current invocation of ack in hex.
    'unique' is a tail unique to this invocation.
2 - The outfile field is used to indicate default naming, can be ovrrriden
    by the -o flag.
3 - Added handling for phases with multiple inputs (ego, linker).

ea6c20f5d1 The role of the combiner is -partially- assumed by the linker. 
Linker arguments are now part of the transformation structure.
Temp file nameing is changed.

2aa5c6b7d9 Variable nregvars had a name clash with the array nregvar[] in the 
file tables.c. That was different in the 8'th character (!"#$%&'()_).
These variables should actually be static.

bbc3cb33cc We do not use the missing " trick anymore. 
The root directory of the EM tree is in the name EM_DIR, the
root directory for tempfiles is in TMP_DIR.
All other path's are relative to EM_DIR.

1c36c470db Increased the amount of information passed through error routines 
to printf. The routine badassert, running on a 2/4 machine lost it's
last argument on the way.
Anyone know of a better way to solve this problem?
