[Bug-ocrad] ocrad-0.7 build feedback

[Nelson H. F. Beebe]

I've just attempted builds of ocrad-0.7 in 45 build environments.
There were 7 successful builds, but the rest had problems, often from
similar causes.

Also, there is a problem in Makefile.in: it is not obeying settings of
CC and CXX made at configure time, but instead is forcing builds with
g++.  Makefile.in MUST have

CC = @CC@
CXX = @CXX@

configure will supply suitable values, defaulting to gcc and g++ if
they are not otherwise set.

Thus, the 45 builds that I attempted were effectively only about 15 or
so distinct builds.

Here is a summary of the problems:
