It seems that the 1.5.25-* versions of Cygwin are built with a
NON-recent-CVS newlib at which are applied a few patches (mainly in math
libs).

Why not using a fresh newlib CVS?

I have rebuild 1.5.25-7 with a fresh newlib CVS (20071215).

To do this I have applied only these patches (realized comparing with
Cygwin snapshot):

The result seems to works fine.


In the build log I have found the following error messages that DO NOT
stop the build process:

[1]
checking for gawk... (cached) gawk
checking for .preinit_array/.init_array/.fini_array support... readelf:
Error: Input file 'conftest' is not readable.
no
checking for array aliasing support... yes

[2]
Error: Version info is older than DLL API!



[1] appears also in the 'pure' rebuild of 1.5.25-7, while [2] appears 3
times.

So the question is: What is wrong in the above? What have I missed?



Thanks... and sorry for the noise,

  Angelo.

[ANNOUNCEMENT] Updated: [experimental] cygwin-1.5.25-7

[Corinna Vinschen]

I've uploaded another test version of the Cygwin DLL and its utilities,
version 1.5.25-7.  It contains all fixes related to what cropped up
since the release of 1.5.25-5 on Sunday.

Changes since test version 1.5.25-6:

- Fix return value of poll().

- Fix file position in append mode for non-Cygwin processes.

- Fix missing definition of struct iovec when including sys/socket.h.

Changes since version 1.5.25-5:

- tzset is now thread safe.

- Fix a problem with spurious memory allocation failure.

- Fix permission settings for directories on non-NTFS file systems.

- Fix NaN and +-inf handling in various math functions.

- Fix a problem with potentially wrong results in tgammaf().

Please test.


To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page.  This downloads setup.exe to your
system.  Save it and run setup, answer the questions, then look for
'cygwin' in the 'Base' category (it should already be selected).  You
will need to use the 'Exp' radio button to get the test version.

If you have questions or comments, please send them to the Cygwin
mailing list.  See http://cygwin.com/lists.html for details.
