w32api funny

[Dave Korn]

  I noticed this when we added StrStrI to setup.exe, and I forgot to bootstrap
the generated files; I got a bad exe that didn't work for me because it
imported StrStrIA from comctl32.dll (which was the next -l option in the
LDFLAGS), which - at least on w2k - doesn't actually export that function:

$ for x in /usr/lib/w32api/lib{comctl32,shell32,shlwapi}.a ; do echo $x; nm $x
| grep StrStrI  ;  done
/usr/lib/w32api/libcomctl32.a
00000000 T _StrStrIW@8
00000000 I __imp__StrStrIW@8
00000000 T _StrStrIA@8
00000000 I __imp__StrStrIA@8
/usr/lib/w32api/libshell32.a
00000000 T _StrStrIW@8
00000000 I __imp__StrStrIW@8
00000000 T _StrStrIA@8
00000000 I __imp__StrStrIA@8
/usr/lib/w32api/libshlwapi.a
00000000 T _StrStrIW@8
00000000 I __imp__StrStrIW@8
00000000 T _StrStrIA@8
00000000 I __imp__StrStrIA@8

$ cd $WINDIR/system32

$ for x in comctl32.dll shell32.dll shlwapi.dll ; do echo $x ; dumpbin
/exports $x | grep StrStrI ; done
comctl32.dll
shell32.dll
        403   AB 00117E97 StrStrIA
        404   AC 00117E9D StrStrIW
shlwapi.dll
        710   F4 0000F2B4 StrStrIA
        711   F5 00007E9E StrStrIW

  I checked on an XP system as well, and it's not exported from comctl32.dll
there either.  The definitions come from here:

/usr/src/w32api-3.13-1/lib/comctl32.def:125:StrStrIA@8
/usr/src/w32api-3.13-1/lib/comctl32.def:126:StrStrIW@8

and are present in CVS HEAD.

    cheers,

I removed all the erroneously defined StrFOO entry points from comctl32.a.

So, not really funny "ha-ha", then... too bad.  I was hoping for an
API knee-slapper.

  Nah, just a funny peculiar.

  I heard that all the kids are into "api slapping" these days...
