[Message part 1 (text/plain, inline)]

Hello libtool devs,

There's a common information/warning message that occurs with building
secp256k1 for example where it states:

*"/usr/bin/ar: `u' modifier ignored since `D' is the default (see `U')"*

This can be resolved if "cru" is changed to "crU" in:

*/usr/share/aclocal/libtool.m4*


Please consider doing this, thank you !

Otherwise the temporary fix for this for code builds is to put
*AR_FLAGS="crU"* in configure.ac

Obviously this would cause problems when 'ar' does not support the 
binutils-specific 'U' option and the result is then non-deterministic. 
Hard-coding non-portable options is contrary to the goals of portable 
software.

The deterministic build may slow down the build process and the 
warning is annoying.  Deterministic builds are a good thing though.

I should mention that binutils ar only produces deterministic archives 
by default if it was configured with --enable-deterministic-archives. 
This is not always the case.
