Description:

When building projects which use CUnit, the compiler does not find CUnit header files. It report errors like:

test-expander-roles.c:27:25: fatal error: CUnit/Basic.h: No such file or directory
#include <CUnit/Basic.h>

This is because bcunit installs files in /usr/include/BCUnit instead of /usr/include/CUnit, and uses a library named libbcunit.so instead of libcunit.so.

Therefore the current bcunit package (version 3.0-1) does not replace the previous cunit package. Moreover as no distribution among Gentoo, Fedora, Debian or Ubuntu provide a BCUnit package (yet), it is difficult to ask the project developers to move to BCUnit.

A simple solution would be to remove the "provides=('cunit')" and "replaces=('cunit')" tags from the PKGBUILD and to keep a cunit package. Another one would be to install compatibility symbolic links /usr/include/CUnit->BCUnit, /usr/lib/libcunit.so->libbcunit.so, etc. A third one would be to create a new "bcunit-cunitcompat" package like systemd-sysvcompat, which installs these symbolic links (this package would depend on bcunit and provide/replace cunit).

Additional info:
* bcunit 3.0-1
* x86_64 architecture

Steps to reproduce:
For example clone libsepol from https://github.com/SELinuxProject/selinux/tree/master/libsepol and build with "make test":
* git clone https://github.com/SELinuxProject/selinux
* cd selinux
* make DESTDIR=$(pwd)/myDESTDIR install
* make SUBDIRS=libsepol DESTDIR=$(pwd)/myDESTDIR test
