+#  Centos users may need to add -std=c99 to the CFLAGS in the ../configure
+#  statement.
 # Options:
-# --adms and --enable-adms will install extra HICUM, EKV and MEXTRAM models via the 
-# adms interface. You need to download and install the *.va files via ng-adms-va.tgz 
-# Please see the ngspice manual, chapt. 13, for more info on adms.
+# --enable-osdi will enable the OSDI interface, which, in conjuction with the
+# external OpenVAF Verilig-A compiler, will allow access to advanced compact
+# device models writen in Verilog-A.
+# Please see the ngspice manual, chapt. 13, for more info on using OSDI/OpenVAF.
 # CIDER, XSPICE, and OpenMP may be selected at will.
 # --disable-debug will give O2 optimization (versus O0 for debug) and removes all debugging info.
