g-wrap fails to build against guile 1.8.4 built with gcc 4.3.
The attached patch for guile-1.8 from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466778 fixes this.
Tested with guile-1.8.4. Not sure about other 1.8.x versions.

patch for guile-1.8
unreleased 1.8.5 will contain gcc-4.3 support:
Please add this patch to 1.8.4 unless release of 1.8.5 is imminent. GCC 4.3 will be in ~arch soon and it would be unfortunate if guile didn't compile at all.
fixed in 1.8.4-r1
