OpenBLAS: 0.3.7 fails to compile with PGI 19.4

After adding HOSTCC=cc I was able to build 0.3.7 with PGI version 18.10. However, for PGI version 19.4, the build fails with compiler error:

My build command was:

make USE_OPENMP=1 CC=pgcc CXX=pgc++ FC=pgfortran F90=pgfortran F77=pgfortran HOSTCC=cc

Any hints would be appreciated.
