I added an output of the CWD and get:
PWD= D:\src\libo\workdir\wntmsci14.pro\UnpackedTarball\langtag\liblangtag
CMD= C:\cygwin\opt\lo\bin\ccache.exe cl.exe -nologo -EHsc -MD -Gy

-DG_LOG_DOMAIN=\"LangTag\" -Zi -c -showIncludes lt-database.c
cl : Command line error D8003 : missing source filename


When I go to the directory, set the PATH according to the one from
config_host.mk, I get :

mm at FAUCON
/cygdrive/d/src/libo/workdir/wntmsci14.pro/UnpackedTarball/langtag/liblangtag
$ /cygdrive/c/PROGRA~2/MICROS~1.0/VC/bin/cl.exe  -nologo -EHsc -MD -Gy

-ID:/src/libo/workdir/wntmsci14.pro/UnpackedTarball/xml2/include
-DG_LOG_DOMAIN=\"LangTag\" -Zi -c -showIncludes lt-database.c
lt-database.c
Note: including file:
D:\src\libo\workdir\wntmsci14.pro\UnpackedTarball\langtag\config.h
lt-database.c(17) : fatal error C1083: Cannot open include file:
'string.h': No such file or directory

Which is a different error.
I get the D8003 when I try to run that in another directory, which makes
me think that although getcwd retrieves the current dir, it may not be the
one use as for launching the command. But CreateProcess should use the
same since the parameter is set to NULL [1].
SO really no clue there.

Nope. I tried both to remove any doubt.

My tree is on  29dcdf6b56f8dbc1b7d, and I did a git clean -fxd before make.

Well, as we tend to support VS 2008, 2010 & 2012 in build setup, we should
have them also supported in gcc-wrapper.
BTW, moved to VS2012 no-express meanwhile
