Ada shared libs issue.

[Pascal]

Hello,

My configuration: GNAT Community 2020 on macOS Catalina.

I've an error with shared lib:
% ./configure CC='gcc -g -O0' --enable-pc-files --with-ada-sharedlib 
--enable-symlinks --prefix=$instxada
% make
...
rm -f AdaCurses.gpr
/bin/sh ./library-cfg.sh dynamic library.gpr -I. -I../include -I../../include  
-I/opt/xnadalib-2020/include -I. -I../include -D_DARWIN_C_SOURCE -DNDEBUG 
-DHAVE_CONFIG_H -I. -O2 -g -O0 --param max-inline-insns-single=1200 -dynamic 
>AdaCurses.gpr
library-cfg.sh: ignored option --param
library-cfg.sh: ignored option max-inline-insns-single=1200
library-cfg.sh: ignored option -dynamic
