configure: WARNING: unrecognized options: --disable-libcurl, --disable-libmms

python2: creates still a lot of these warnings while compiling some sub libs

sidplay-libs: configure: WARNING: unrecognized options: --disable-library-checks - some error at their code

How to check:

awk.cfg

/^\s*\033\[.*mBUILD\033\[.*m/ {
  PKG=$2
  TRG=$3
  sub(/^.*\(/, "", TRG)
  sub(/\).*$/, "", TRG)
}

/^configure: WARNING: unrecognized options: --disable-static, --enable-shared$/ { next }
/^configure: WARNING: unrecognized options: --disable-static$/ { next }
/^configure: WARNING: unrecognized options: --enable-shared$/ { next }

/^configure: WARNING: unrecognized options:/ {
  printf "%-20s: %s\n", PKG " (" TRG ")", $0
}

awk -f awk.cfg le-build-output.log
