fixed some minor gcc-2.95.3 build issues
Added support for building tuxpaint on Haiku
This now allows tuxpaint to build on a gcc4 Haiku.
Adding the tuxpaint.rdef file, this contains the tuxpaint icon for Haiku
Fixes for parse.gperf on gcc2 Haiku build (perhaps others?).
Small gcc2 fix.
Fixed several gcc2 errors, and a handful of warnings.
Find the font directories on Haiku. This was left off a previous patch somehow.
