Weird configuration summary for hash libs

I'm building nginx from the source and I've just noticed a weirdness at the end of the ./configure run, both for 1.2.8 and 1.3.16, the summary doesn't seem to match the checks above:
checking for system md library ... not found checking for system md5 library ... not found checking for OpenSSL md5 crypto library ... found checking for sha1 in system md library ... not found checking for OpenSSL sha1 crypto library ... found checking for zlib library ... found creating objs/Makefile Configuration summary + using system PCRE library + OpenSSL library is not used + md5: using system crypto library + sha1: using system crypto library + using system zlib library
There seems to be a contradiction between 'checking for system md5 library ... not found' and 'md5: using system crypto library' (same for SHA1).
I've traced it to the following configuration script: auto/lib/md5/conf, line 83:
if [ $ngx_found = no ]; then # OpenSSL crypto library ngx_feature="OpenSSL md5 crypto library" ngx_feature_name="NGX_OPENSSL_MD5" ngx_feature_incs="#include <openssl/md5.h>" ngx_feature_libs="-lcrypto" ngx_feature_test="MD5_CTX md5; MD5_Init(&md5)" . auto/feature ngx_md5_lib="system crypto" if [ $ngx_found = yes ]; then have=NGX_HAVE_OPENSSL_MD5_H . auto/have have=NGX_HAVE_MD5 . auto/have fi fi
The 'ngx_md5_lib' variable should probably be set to something else to reflect the use of the OpenSSL library. In auto/lib/conf, it is set to 'OpenSSL' when the OpenSSL library is used. I understand that OpenSSL as a library isn't used in my case, but maybe something more descriptive like 'system crypto (OpenSSL)' would feel better here.
The scripts for SHA1 are very similar.
