Parts of this package are going to have to be C++ in the GNU world because we

now use exception handling to implement thread cancellation. The MSC compiler
appears to know about __try/__except blocks, but gcc (ie. the GNU ANSI C
compiler) doesn't know about the equivalent C++ try/catch blocks. This should
not be a problem since gcc and g++ are nearly always available together. Some
file names may need to change in the CVS repository however.
Tue Jan  5 16:33:04 1999  Ross Johnson  <rpj@swan.canberra.edu.au>
        * cleanup.c (_pthread_pop_cleanup): Add C++ version of __try/__except
        block. Move trailing "}" out of #ifdef _WIN32 block left there by
        (my) mistake.
        * private.c: Remove #include <errno.h> which is included by pthread.h.
