Corrected an unfortunate issue in the gf180mcu.tech file for magic
in which the syntax used for the preprocessor is not recognized
by the preprocessor, causing a number of rules for 1.1um thick
metal to be output as rules for 0.9um thick metal instead.  Thanks
to Tamas Hubai for catching this error.  Also:  Recently updated
the xschem symbols for gf180mcu to add the "s_sab" and "d_sab"
properties to the "_dss" FET devices (drain-side salicide block).
Otherwise, the schematic devices are incompletely specified and
will fail property matching in LVS.  So the git hash reference
for the repository has been updated in open_pdks.
