Building guile-1.4 fails with an AWK internal error?
This is a known problem when building guile-1.4 with a comparatively recent version of GCC. Between Guile versions 1.4 and 1.6, GCC’s preprocessor behaviour changed so that macro expansions go on a single line in the output, which doesn’t agree with Guile 1.4’s doc snarfing mechanism. From 1.5.x onwards we implemented a new doc snarfing mechanism that copes with this. Obviously we can’t fix the 1.4 distribution retrospectively. So the fix is either to downgrade to an older GCC or to move to guile-1.5.x, or Guile 1.6 when that becomes available.
