[Mingw-cross-env-list] netcdf undefined references from libcrypt32

[Richard Crozier]

Dear List,

I'm trying to build a package based on autoconf which links to netcdf, 
netcdf is not detected by configure for the cross build. Looking at the 
config.log I see the following faled test program:

configure: failed program was:

undefined reference to `__imp_CertEnumCertificatesInStore'


some googling indicates that these references are from libcrypt32 (I'm 
basing this on the following link):

https://github.com/openssl/openssl/issues/1061

I did git pull on mxe before this error, so I should be using the latest 
version.

Can anyone advise on how to proceed?


Regards,

Richard
