This is an automated email from the git hooks/post-receive script.
sthibault pushed a commit to branch upstream
in repository hurd.
commit 74f4e5781e0f259a22b8e1e125973262600abed7
Author: Justus Winter <address@hidden>
Date: Fri Jun 2 17:23:03 2017 +0200
trans: Conditionally build the random translator.
Only build the random translator if we find a suitable version of
libgcrypt. This helps to reduce the build dependencies to bootstrap
the Hurd.
* aclocal.m4: Include 'libgcrypt.m4'.
* config.make.in (HAVE_LIBGCRYPT): New variable.
* configure.ac: Check for a suitable libgcrypt.
* m4/libgcrypt.m4: New file.
* trans/Makefile: Conditionally build the random translator.

+dnl AM_PATH_LIBGCRYPT([MINIMUM-VERSION,
+dnl [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND ]]])
+dnl Test for libgcrypt and define LIBGCRYPT_CFLAGS and LIBGCRYPT_LIBS.
+dnl MINIMUM-VERSION is a string with the version number optionalliy prefixed
+dnl with the API version to also check the API compatibility. Example:
+dnl a MINIMUM-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 feature prevents building against newer versions of libgcrypt
+dnl with a changed API.
+dnl
+dnl If a prefix option is not used, the config script is first
+dnl searched in $SYSROOT/bin and then along $PATH. If the used
+dnl config script does not match the host specification the script
+dnl is added to the gpg_config_script_warn variable.
