slightly modified by me.
Changes since 0.6:
* Ported to Solaris 2.8.
* Added a new error source GPG_ERR_SOURCE_GSTI, and new error
codes GPG_ERR_PROTOCOL_VIOLATION and GPG_ERR_INV_MAC for this
source.
* Interface changes relative to the 0.7 release:
GPG_ERR_SOURCE_GSTI NEW
GPG_ERR_PROTOCOL_VIOLATION NEW
GPG_ERR_INV_MAC NEW
GPG_ERR_INV_REQUEST NEW
* libgpg-error can be built on systems where the errno macros do not
evaluate to plain numbers, but expressions. If you want to
cross-compile, you might have to set CC_FOR_BUILD, though.
* A new tool gpg-error to convert error numbers into symbols into
strings is provided.
* Interface changes relative to the 0.6 release:
GPG_ERR_LOCALE_PROBLEM NEW
GPG_ERR_NOT_LOCKED NEW
