The library contains a header file "strings.h" which gets pulled in
by <string.h>, leading to lossage. Defining ANSI_SOURCE used to help,
but now we don't get an mkstemp() prototype anymore if this is defined,
leading to compile problems at another place...
So finally rename the pkg's strings.h.
Being here, update to ...pre2, the changelog is
* Many bug fixes -- mostly compilation problems -- more detailed info will be
provided in a later release.
