RE: Proposed patch for '-version-number' option for libtool

[Boehne, Robert]

Keith,

You're close, but there are a couple issues before this is
"prime time" material,
 
1st: new flags have to have documentation, as we discussed before it
should be made very clear what this flag is intended to be used for.

2nd: The problem with libltdl/configure.ac is in Automake, 1.4-p6 is quite
old, the most recent version is 1.7.2, in which I've never seen a
file named config-h.in] get created.

So, strip the configure.ac part, and write some documentation (add to 
doc/libtool.texi)
and it's finished.

Thanks,

Robert Boehne

Subject: Proposed patch for '-version-number' option for libtool



To permit automake and libtool to replace imake and other legacy build 
environments, explicit version numbering of libraries is required.  This
patch adds a '-version-number' option to libtool which computes approprate 
current, age and revision values for each supported build environment so 
that the resulting library version numbers match those provided.  This
round-about mechachanism was selected mostly to ensure .la file 
compatibility.   An additional benefit is that the changes are small and 
localized; future changes to the system will probably not require any 
maintenence of this feature.

I also found a problem in the configuration scripts when building libtool 
with autoconf 2.57 and automake 1.4-p6; a fix for that is enclosed at
the bottom of this patch.
