[open-cobol-list] CVS update (11) - Add bin/cobcrun

[Roger While]

Added bin directory with contents :
cobcrun.c
Makefile.am
Makefile.in
ChangeLog

Syntax : cobcrun MYPROG [arguments to MYPROG]
Assumes all app prgrams have been compiled as modules.

To get this into the configure/make process, I had to
run this through aclocal/autoconf/automake, so there are
minor (auto-genned) changes to several files (mainly Makefile.xx).

The Makefile.am looks like this :

bin_PROGRAMS = cobcrun
cobcrun_SOURCES = cobcrun.c
AM_CFLAGS = $(COB_EXPORT_DYN) -Wall -Wwrite-strings -Wmissing-prototypes 
-Wno-format-y2k
cobcrun_CFLAGS = $(AM_CFLAGS) $(COBC_CFLAGS) -I$(top_srcdir)
cobcrun_LDADD = $(LIBCOB_LIBS) \
$(top_builddir)/libcob/.libs/libcob_la-call.o \
$(top_builddir)/libcob/.libs/libcob_la-numeric.o \
$(top_builddir)/libcob/.libs/libcob_la-common.o \
$(top_builddir)/libcob/.libs/libcob_la-screenio.o \
$(top_builddir)/libcob/.libs/libcob_la-fileio.o \
$(top_builddir)/libcob/.libs/libcob_la-strings.o \
$(top_builddir)/libcob/.libs/libcob_la-move.o \
$(top_builddir)/libcob/.libs/libcob_la-termio.o

Of note here is :
COB_EXPORT_DYN which is pulled out of the top level configure from
"export_dynamic_flag_spec".
I was hoping I could use "whole_archive_flag_spec", in which case we could 
have used
the archive library instead of the components of the library, but libtool 
does it wrongly
(Reported elsewhere on the Web).

Also the complete OC runtime library is statically linked in (We don't have 
any other
choice). This has the advantage that, after a configure/make (but not 
install), we can test
an app with this OC by calling the compiler from the cobc directory and 
running it by calling
cobcrun from the bin directory without disturbing any installed OC.
This is possible while the OC runtime library is completely within cobcrun 
(and symbols exported)
so that no reference should be made at runtime to an installed shared OC 
library. (I hope)

No other existing functionality is changed/disturbed by this.

Please test and report back.
