Hi MUHAMMAD-san.

Sorry late reaction...

However, There is a thing of now a few.

I have a comment from Ralf S. Engelschall.

Sorry for being late with the release of OSSP uuid 2.0.0.
Yes, it will be released the next days and will contain the
Win32 support I already prepared a few months ago.

It seems that link http://winpg.jp/~saito/pg_work/OSSP_win32/msvc/ is no longer available. I 
am working on uuid-ossp contrib module, I want to share my findings with you.Thanks.
I have downloaded uuid-1.6.2.tar.gz from http://www.ossp.org/pkg/lib/uuid/ . It successfully 
built with MinGW gcc and made libuuid.a, I renamed it to uuid.lib to build uuid-ossp contrib 
module with visual studio 2005. uuid-ossp give the following linker error with VC2005 i.e.

Linking...
Creating library Release\uuid-ossp\uuid-ossp.lib and object Release\uuid-ossp\uuid-ossp.exp
uuid.lib(uuid_time.o) : error LNK2019: unresolved external symbol ___divdi3 referenced in 
function _uuid_time_gettimeofday
uuid.lib(uuid_time.o) : error LNK2019: unresolved external symbol ___moddi3 referenced in 
function _uuid_time_gettimeofday
uuid.lib(uuid_str.o) : error LNK2019: unresolved external symbol ___umoddi3 referenced in 
function _fmtint
uuid.lib(uuid_str.o) : error LNK2019: unresolved external symbol ___udivdi3 referenced in 
function _fmtint
.\Release\uuid-ossp\uuid-ossp.dll : fatal error LNK1120: 4 unresolved externals

MinGW libgcc.a contains these symbols and these routines are not implemented in c ( its 
assembly code to make it fast ) so I extracted _divdi3.o _moddi3.o _umoddi3.o _udivdi3.o (we 
can add these additional files to uuid.lib to make build easy) from libgcc.a and link it 
with uuid-ossp contrib. I have tested generated uuid-ossp contrib it gives the following 
results that seems fine i.e.

edb=# select uuid_generate_v4();
uuid_generate_v4
--------------------------------------
20ff31ce-77a8-4db6-ac7f-3b55380e46ac
(1 row)


edb=#
edb=# select uuid_generate_v4()
edb-# ;
uuid_generate_v4
--------------------------------------
e58c46d5-7161-47ec-8006-f905c6b66a1f
(1 row)

Any thoughts on this ?.
