Thank you! :)
What is the rational for having --with-zlib but --with-libz-prefix
(ie zlib vs libz) ? Looks not very consistent.

Hello,
This patch enhances config/zlib.m4 to introduce an extra option
--with-libz-prefix which allows us to provide the location of
the zlib library we want to use during the build.
config/ChangeLog:
* zlib.m4 (AM_ZLIB): Add --with-libz-prefix option support.
I didn't see any file in the GCC project that uses this macro,
so for the GCC repository, the change to zlib.m4 is it. But
I am also attaching to this email a copy of the patch that
will be applied to the binutils-gdb.git repository, with all
configury using this macro being re-generated - mostly for info,
also as a heads-up to both binutils and GDB.
This was tested by regenerating all autoconf/automake files in
the binutils-gdb project, and rebuilding GDB, using the following
combinations:
--with-zlib (system zlib used)
--with-libz-prefix=/zlib/prefix (specific zlib linked in)
--with-zlib --with-libz-prefix=/zlib/prefix (specific zlib linked in)
--without-zlib (zlib support turned off)
--without-zlib --with-zlib-prefix (zlib support turned off)
--with-zlib (no system zlib available, configure fails with expected error)
--with-zlib --with-libz-prefix=/invalid/zlib/prefix
(no system zlib, configure fails with same error)
