you would need to run perl on it or something before, macro won't work

The only way I can make this work is using perl -pi.bak -e "s/...//gm;" main.c then run gcc instead of #define macros 🤷♂️
UTF-8 Bash only, broken in MS-DOS console:
perl -pi.bak -e "s/[ ]*(#define)[ ]+[╔║╚═╝╗]+.*$//gm;s/[╔║╚═]+//gm;s/[╗]/{/gm;s/[╝]/}/gm;" main.c
# Same program long verbose formatting of implicit accumulator stdin execute then print in place loop
while($_ = <STDIN>)
{
$_ =~ s/[ ]*(#define)[ ]+[╔║╚═╝╗]+.*$//gm;
$_ =~ s/[╔║╚═]+//gm;
$_ =~ s/[╗]/{/gm;
$_ =~ s/[╝]/}/gm;
print $_;
}
