* autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
  causing e.g. the libgig test to fail when
  "./configure --disable-jack-driver" was used
  (patch by Alexis Ballier)

11     # The following is the libtool / shared library version. This doesn't have to
12     # do anything with the release version. It MUST conform to the following rules:
13     #
14     # 1. Start with version information of `0:0:0' for each libtool library.
15     # 2. Update the version information only immediately before a public release of
16     # your software. More frequent updates are unnecessary, and only guarantee
17     # that the current interface number gets larger faster.
18     # 3. If the library source code has changed at all since the last update, then
19     # increment revision (`c:r:a' becomes `c:r+1:a').
20     # 4. If any interfaces have been added, removed, or changed since the last update,
21     # increment current, and set revision to 0.
22     # 5. If any interfaces have been added since the last public release, then increment
23     # age.
24     # 6. If any interfaces have been removed since the last public release, then set age
25     # to 0.

891     Depending on compiler and platrofm this could
892     perform better than integer math as it avoids
893 schoenebeck 1360 an extra integer multiply instruction.

896     sinusoidials. This solution might especially hurt on
