I've worked with much more than eight platforms -- I was referring to eight
different types of shlibs with different link procedures (not just different
"link options"). If I include the variants on iBCS2, Sun-style, ELF, and
PE-COFF, the list would get much longer. And yes, that list gets far too
long to maintain on a per-project basis.

I fail to see how what is essentially a compiler wrapper script is any worse
off than automake makefile fragments. A compiler frontend script is far
more flexible to use, actually; it permits usages outside the scope of
automake, which is too policy-foisting for many folks.

If you track back, this ranting about libtool's [perceived, by you]
shortcomings was your posit, and my main point in response (before I went
into troll-feeding entertainment mode) was that it provides, today, a
workable solution that actually puts an effort forward to document when to
deal with different types of ABI changes. It's at that point that you
decided to ignore that point entirely and go off on the tangent of
destructively bashing libtool rather than doing something constructive with
