svn commit: r1087184 - in /apr/apr/trunk/build: NWGNUenvironment.inc NWGNUmakefile make_nw_export.awk

[fu...@apache.org]

Author: fuankg

New Revision: 1087184

URL: http://svn.apache.org/viewvc?rev=1087184&view=rev
Log:
Removed dependency on sort command for export list.

Added a shell sort function to the NetWare export script
which is only few ms slower than the external sort command;
this makes the export list now identical on all build platforms.
