Write an xrealloc wrapper that works the same way, and use it as well.
People who feel like it may want to add more explicit error messages to
all the places m4 can fail allocating memory...

Inline some macros/functions for speed.
So, this achieves the goal of one single lookup for macro/trace status,
which does speed up m4 in partial tracing situations somewhat.
This does also speed up m4 in large pushdef situations, since it no longer
has to lookup large chains of macros.

Fold built-in lookup into normal lookup.

make the stack structure of macro definitions explicit.

define an interface with explicit define/pushdef/popdef... and use it.
That way, most details of the hashtable are no longer visible.

hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

o Add a missing 'unsigned' to 'h' in remhash()
o Say 'unsigned int' not just 'unsigned'
|
|
With 2^32 possible hash values, this means that collisions no longer
incur supplementary string compares, which was most of the reason for
STREQ in the first place...

Add missing prototypes,
Make local functions static,
Sort extern.h by file,
Constify all char * that can be,
Copy temp file name so that eval does not modify its arguments.

Let indx match netbsd flavor, to simplify diffs.
Show how many quotes were not closed.
Increase stack slightly, now that we're no longer bound by argspace.
|
|
- use err.h and kill oops,
- use __progname and kill basename,
- let indx use strstr
- proper EOS decl
