Compile libpq with vc8

Hi,
 I am trying to compile libpq with vc8. I got errors in wchar.c

..\..\backend\utils\mb\wchar.c(99) : error C2054: expected '(' to follow 
'inline'
..\..\backend\utils\mb\wchar.c(100) : error C2085: 'pg_euc_mblen' : not 
in formal parameter list
..\..\backend\utils\mb\wchar.c(100) : error C2143: syntax error : 
missing ';' before '{'

 If I remove the "inline", I got an error in:

[...]postgresql-8.1.4\src\include\utils/elog.h(105) : error C2365: 
'errcode' : redefinition; previous definition was 'typedef'
 Does anyone already compiled libpq with vc8?

Yannick.
