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

[Angelo Graziosi <Angelo dot Graziosi at roma1 dot infn dot it>]

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.
