Issue #2065: VC6 related fix.

- PC/VC6/_bsddb.dsp:
    removed '/nodefaultlib:"msvcrt"' to fix linker error.

- PC/VC6/_sqlite3.dsp:
    /D "MODULE_NAME=\"sqlite3\""
    caused extra leading space like
    #define MODULE_NAME " sqlite3"
    so uses
    /D MODULE_NAME=\"sqlite3\"
    instead.

- PC/VC6/python.dsp:
    changed the way of modifying stack size
