Compiling with MSC32, I see the switch -TP in each line of the log. This
is the first:

CL -D__WIN32__ -D_HAVE_SQLITE_CONFIG_H -DHAVE_CONFIG_H -DHARBOUR_CONF
-DOPENSSL_NO_DEPRECATED -DHB_NO_DV_MEMCPY -DHB_NO_BACKGROUND -DHB_GUI
-I"source\rtl\zlib" -I"contrib\pdflite\include" -I"contrib\png"
-I"contrib\tiff" -I"contrib\jpeg" -I"include" -I"e:\msc32\msc\include"
-I"obj\vc32" -I"contrib\sixapi\include" -I"contrib\freeimage\include"
-I"contrib\gd\include" -I"contrib\xwt\include"
-I"contrib\xwt\src\xwt_win" -c -GA -Gs -EHsc -nologo -Otyb1 -W4

-D_CRT_NONSTDC_NO_DEPRECATE -MD -MP -O1 -W4 -WX -TP -Foobj\vc32\hbrm.obj
utils\misc\hbrm.c

If I am not missing something, why are we compiling the whole xHarbour
in C++ mode?

This is a very old issue, IIRC it had to do with a way to be able to set
initialization code in C for MSC, (like INIT PROCEDURE in Clipper).

There was no standard way to set initialization, and each compiler
has/had its own trick. You may review hbinit.h
