Subject: Avoid gcc/10.1.0 bug by moving some configuration into a namespace
X-Git-Tag: cvc5-1.0.0~578
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=966407c1490695bdac2a4d95397625adbcce433a;p=cvc5.git

Avoid gcc/10.1.0 bug by moving some configuration into a namespace

Eventually there is intention to move all of cvc5::Configuration into
cvc5::configuration, this is a first step that also has the nice side-effect of
letting it build under an otherwise-buggy version of gcc/10.1.0 that was
causing issues.
