Be more forgiving with relative paths in search dirs #88

If a search dir is relative and starts by '..', the current code is going
to crash. Instead, accept it without normalizing it.

Sorry for the slow response time. Out of curiosity, have you actually seen this crashing?

To answer your question, yes we saw this crashing. However we are building in a very specific env:

  • regular MinGW compiler (i.e. not the "cross" one from Cygwin)
  • tons of systems libraries at non-standard paths.
    So I cannot extract a repro case, I'm afraid.

I rebased and pushed a minor variation which does not use when. Apologies for the back-and-forth.

We should only get absolute library paths in search dirs, but
sometimes we currently get ./../lib. Accept this case

Thank you for swift update! That looks great to me. No problem about the repro - I was only curious as to whether you'd got a "real" setup which hit this, or if you'd just noticed it reading the code.

I shall shortly tag 0.40, which will include this.
