undefined reference to `Curl_month' when configured with --disable-dateparse

[rohieb]

I did this

• downloaded and extracted curl 7.66.0
• ./configure --disable-dateparse && make -j20, but make throws errors:

  CCLD     curl
/usr/bin/ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_wkday'
/usr/bin/ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_month'

I expected the following

No errors.

curl/libcurl version

7.66.0, reproducable with 7.65.4

operating system

Debian GNU/Linux 10 (buster)
