You basically omitted all useful details, especially where to get those
pkgutils and what the code around line 75 looks like. Also don't post
private mails to this list please.
The code looks like this (useless bits deleted):
int fd = open(filename.c_str(), O_RDONLY);
stdio_filebuf<char> filebuf(fd, ios::in, getpagesize());
stdio_filebuf is GNU extension (god kills a kitten for every GNU
extension, please don't write extensions, think of the kittens!)
to libstdc++ which is part of GCC.
The constructor declaration from gcc 3.3.5 look like this:
stdio_filebuf(int __fd, std::ios_base::openmode __mode, bool __del,
size_t __size);
Looking at the same thing in a very recent gcc version (4.3), it looks
like this:
stdio_filebuf(int __fd, std::ios_base::openmode __mode,
size_t __size = static_cast<size_t>(BUFSIZ));
__del means close the file and is now always true.
stdio_filebuf<char> filebuf(fd, ios::in, true, getpagesize());
should do the trick (untested)
Of course all of this has nothing to do with OpenBSDs libc, but with
people who change APIs without thinking...
