 | |
| dnl MINIMUN-VERSION is a string with the version number optionalliy prefixed
 | |
| dnl with the API version to also check the API compatibility. Example:
 | |
| dnl a MINIMUN-VERSION of 1:1.2.5 won't pass the test unless the installed 
 | |
| dnl version of libgcrypt is at least 1.2.5 *and* the API number is 1.  Using
 | |
| dnl this features allows to prevent build against newer versions of libgcrypt
 | |
| dnl with a changed API.
