glibmm 2.4.5 unpacks properly. glibmm 2.4.6, glibmm 2.6.0 and glibmm 2.8.4 
error with SIGPIPE.

Not if he uses cygwin, which has at least 1.15. The environment I'm using is 
mingw, and the packaged tar version is 1.13.19, i.e. older than May 2004 which 
is the release date of 1.14 [1].

As the error seems to appear for glibmm 2.4.6 (tarball is from end of January 
2005 [2]), it does seem it is related to this bugreport dating from December 2004.

The fact was that an unpacked and repacked tarball was half as big, which was 
a rather strange expansion. If you unpack 2.8.4 tarball [3], and search 
occurences of the string "glibmm-2.8/" (NULL included) in the .tar file, you 
find 2 occurences:
- 0x0
- 0xA14000, i.e. 10567680, which is very close to being half of the 21155840 
bytes of the file
The following bytes are identical, I tend to suspect that the second half is 
very close to the first one. Now, I don't know the tar file format, but this 
is really strange.

In the end, I haven't been able to find any newer tar version available as a 
stand-alone (i.e. not from cygwin). bunzip'ing then untar'ing does the job though.
