A new checkout and build of (branchi) tag -r bde2alpha_rv.

==========================================
aareadme in ~lechner/bde2alpha_rjl/bde - RJL 2k0827

Rev 2k0918:
-------------------------------------------------------
Note the results in ~/97f522/asgnt1_stsang_dfan
show that genv11 (and v10.2 of Costell) both break make runs
even for simple schemas with gcc -Wall. 
Use of gcc -fno-strict-prototype or gcc -traditional made no diff.

TBD: upgrade chgenv11 to fix the errors that were fixed by hand
in bde2alpha. Meanwhile, check out ntansala's version.
-----------------------------------------------------

Rev. 2k0902.0300: Some stats on pr_util changes (for chgen TBD):
-------------------------------
saturn.cs.uml.edu(321)> cat  old.vs.new.dif | grep ^> | wc
Missing name for redirect.
saturn.cs.uml.edu(322)> cat old.vs.new.dif | grep '^>' | wc
       615      3849     34001
saturn.cs.uml.edu(323old.vs.new.dif | grep '^<' | wc
       360      1992     20219
saturn.cs.uml.edu(324)> so 30 old lines changed to 60 new and not found.
saturn.cs.uml.edu(325)> wc old.vs.new.dif
      1456      6400     55271 old.vs.new.dif
--------------------------------

Rev. 2k0902.0215:
Modified nodeops, hlink and graphobject.cc files - RJL 2k0901.2000 
Fixed arg-passing indirection errors (pr_set_key to decode_retstr);
Removed all *.o and rebuilt bde from schema.h and pr_*.c (not .sch).
The bde root directory now occupies 16.2 MB with one bde.exe (8MB) 
AFTER deleting al *.o files.

Rev. 2k0831: All src fles compile now; ld resolves all symbols.
A new bde executable was generated for the first time this month!
it now exceeds 8 MB, rather than 5!

Rev. 2k0829: All pr_util files now have no warnings from g++ -Wall,
except for a pr_add macro complaint in pr_log and 8 rcsid non-use msgs.
The rcsid's are from the genmerge version and identify src and obj file
versions (using the 'ident filespec' cmd.)

bde/src compile aborts in bendpt.cc with  signature conflicts
(The pr_add complaint appears in bendpt.cc also.
RJLRef: bdemake_2k08290.0310

TBDs: Try extern "C" to avoid name mangling
Compare pr_add to other pr_* protos for "C" context
apply g++ command to other src/* to see if widespred pblm
check bde/src/CS/Tag for T or N value.
COpare schema.h to prior ones; 
consider cvs module to save pr_util which is auto-generated not checked in/out.

------------------------------------------
Rev. 2k0828.0240: all pr*.c routines are error-free except pr_log.c.
See bdemake_2k0828.0240 (82 lines)

-------------------------------------------
Rev 2k0827:	see bdemake* files for compilation logs, 2ksu.
See bde2alpha_rjl/bde/pr_util/aareadme for pr_load.c.2k0827.1600
for fixes to that file. - RJL 2k0827

In ~/bde2alpha_rjl/bde:

Rev. 2k0322 - RJL :
I reran xmkmf  -a after #defining USEGENV11 in bde/configure.h
and #defining GENVERSION as GENV11  in bde/Imakefile - RJL 2k0322

bde recoverd from the grab loop inside gdb!
I was able to move one GX line but when I added line 2
it disappeared when I tried moving line 1.

Here is the crash dump:
-------
Program received signal SIGSEGV, Segmentation fault.
0x120028488 in Ggroup::addcaption (this=0x14011b1c0, x=126, y=364, shape=97)
    at graphobject.cc:875
875         pr_set_key(CG_elt, HGid, HGcurr->HGid);     // int --> key 95/12/6 - RJL
-----------
From Kimball:The X Toolkit Cookbook,
	XtDispatchEventToWidget () is new in X11R6.
I suspect #4  0x3ff8039eb30 in _XtOnGrabList ()
is a wait loop unti a mouse event comes in. 
Then XtDispatchEventToWidget is called inside X11.


Rev. 2k0616 330AM: New bde build with setenv CXX g++ and make -e:
alphja/bde.exe built OK. Many warnings in typescript.
New version of fprint.cc used - to be tested.
(I corrected bde2alpha_rv version bug within fprintf by : \\(%s ----> (%s.. )

fprint testing is TBD;
also modified: 2kfbde_schema.sch (commments and TBD statements added).

TBD: more fprint fixes and gvar additions to schema.

Rev 2k0716, 8:25PM: The first pr_load.o file since I began -Wall removal.
Others compiled for  several weeks now.
Syndrome: hard-to-read '}' masquerading as ')' 
and truncating the macro pr_gen_pkey or pr_gen_key. 
Other bugs: 
	confusing ttabbr the stringized  #XX with char* ttabbr or "XX".
	confusing printf() formatting requirements and casts.
