Compile Proj4 reprojection library on Solaris 11 using Oracle Developer Studio 12.5

This is a follow on from my posts about installing PostGIS in those posts I used GNU compilers, but I have managed to get parts to compile with Developer Studio 12.5.

If you are looking for the GNU version then it is here: Compile PostgreGIS (Proj4 reprojection library) on Solaris 11 (11.3) using gcc

# pkg install build/gnu-make 
# pkg install libtool automake autoconf gnu-gettext library/libxml2 library/json-c

# export PATH=/opt/developerstudio12.5/bin:/usr/bin:/usr/sbin:/usr/sfw/bin:/usr/lib:/usr/gnu/bin:

# unzip -q proj.4-master.zip 
# cd proj.4-master
# autoreconf -vif

#  ./configure CC='cc -m64 -D_XOPEN_SOURCE=600' CXX='CC -m64'  CPPFLAGS=-m64 CXXFLAGS=-m64 --prefix=/usr/local/postgres/proj4s
# gmake
# gmake install

As you can see the main difference is I am using _XOPEN_SOURCE=600 which tells the compiler to include definitions for some extra functions that are defined in the X/Open and POSIX standards.

Without the above you would see the following errors:
