Subject: [PATCH] Add minimal support for --{enable,disable}-{shared,static}
|
|
mpdecimal uses autoconf, but not automake or libtool, so this commit
|
adds some basic handling of --{enable,disable}-{shared,static}, so
|
that building the shared library can be disabled in pure static
|
library contexts.
