L.S.,

I've made a patch against PostgreSQL 7.4.3 to be able to
compile 'libpq'  and 'psql'  with Digital Mars C++.

As Digital Mars C++ doesn't support 'popen()' and 'pclose()'
calls (yet), I was in need to patch some psql .c files to let
them work well with the Digital Mars C++ port.

One needs MSYS and mingw32-make to patch and compile the
postgres sources. The Makefiles (Makefile.sc) are GNU Makefiles. 

Read doc/README.dmc in the postgres source tree and follow
instructions.

One can apply the patch doing:

    tar xzf postgresql-7.4.3.tar.gz
    cd postgresql-7.4.3
    patch -p1 <pgsql-7.4.3-dmc.patch

Best regards,

Hans Oesterholt-Dijkema

+Introduction
+************
+
+This readme file addresses the client port of PostgreSQL 
+for the Digital Mars C(++) Compiler
+
+Prerequisites
+*************
+
+You will need following packages to compile libpq and psql
+with Digital Mars C(++):
+
+	Digital Mars C(++) >=8.34
+	MSYS >=1.0
+	GNU Make for WIN32 >=3.75 ==> mingw32-make will do the job.
+
+
+
+Makefiles
+*********
+
+To compile the client library 'libpq.lib' and the client
+program 'psql.exe' with Digital Mars C(++), the following
+have been added to the PostgreSQL source directories:
+
+	src/Makefile.sc
+	src/Makefile.sc.in
+	src/bin/psql/Makefile.sc
+	src/interfaces/libpq/Makefile.sc
+	
+To change the default settings for these Makefiles, edit
+'src/Makefile.sc.in'. This makefile contains the default
+paths, prefixes, etc.
+
+
+
+		
+Compiling
+*********
+	
+Important to note is following:
+
+When you have entered the MSYS shell, using 'make -fMakefile.sc' 
+won't work, because of UNIX shell incompatilities with some
+DMC programs, notably:
+
+	lib.exe
+	link.exe
+	
+So you will have to do the following:
+
+
+	1. Run the MSYS shell
+	2. Type:
+		cd <Postgresql Source Base Directory>
+		cd src
+		vi Makefile.sc.in
+		mingw32-make -f Makefile.sc
+		mingw32-make -f Makefile.sc install
+		mingw32-make -f Makefile.sc clean
+
+That's all.
