[Mingw-users] bug in mingw?

[Axel V. <vol...@ib...>]

Dear all,

couple of days ago I sent the source of a program which produces a
segmentation fault within the cygwin-environment in connection with
mingw(quoted in this message).

Thank you all for your answers! They helped, because indeed, the segmenta=
tion
fault does not occur while using a pure mingw-environment. But all my stu=
ff is
related to cygwin. So I would like to keep this system.

Weeks ago I got my mingw from
ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygwin/gcc-2.95.2/gcc-2.95=
.2-mingw-extra.tar.gz.
Apparently, Mumit created an easy-to-use package for cygwin with mingw-ve=
rsion
0.3.=20

Finaly, my question: How can I create/get/produce this package with
mingw-version 0.5?


Again, thank you very much in advance and best regards

Axel
