#35 [Patch] to fix LIBM in configure and c89 issues with barcode

[Scott McCreary]

To get gocr to build on Haiku I had to patch so that it wouldn't use -lm which isn't needed on Haiku. Also I had to fix a few variable declarations in barcode.c so that it would compile with gcc2.95.3, which is uses on Haiku to maintain compatibility with BeOS.
