One problem we are encountering with rxtx is libc5 versions of the jdk native
include files are not compiling clean with rxtx. If anyone able to dig around
has the libc5 version installed we are interested in knowing if this is a
problem with the libc5 jdk jni or rxtx.
The only think on the rxtx side I can think of is maybe the flags -ansi
-D_POSIX_SOURCE -D_BSD_SOURCE could be causing problems with the jdk jni. It
works fine on the glibc version.
This was not a problem with previous releases of the libc5 jdk/rxtx when I had
libc5 systems around. There have been proposed changes to typedefs_md.h but
I'm not convinced they are right.
