cvs-1.11.10 win32 VC98 cannot find "assert" during build

[David Everly]

The following command builds cvs-1.11.9, but not cvs-1.11.10 under
windows:

   nmake /f cvsnt.mak CFG="cvsnt - Win32 Debug"

The failure appears to be:

        link.exe @c:\temp\nma01012.
filesubr.obj : error LNK2001: unresolved external symbol _assert
.\WinDebug/cvs.exe : fatal error LNK1120: 1 unresolved externals
NMAKE : fatal error U1077: 'link.exe' : return code '0x460'
Stop.

There is related information about "assert" earlier in the build
log:

        cl.exe /nologo /MLd /W3 /Gm /GX /Zi /Ob1 /I "windows-NT" /I
"lib" /I "src" /I "zlib" /D "_DEBUG" /D "WIN32" /D "_CONSOLE" /D
"HAVE_CONFIG_H" /Fp".\WinDebug/cvsnt.pch" /YX /Fo".\WinDebug/"
/Fd".\WinDebug/" /c ".\windows-NT\filesubr.c"
filesubr.c
.\windows-NT\filesubr.c(766) : warning C4013: 'assert' undefined;
assuming extern returning int

My compiler is Microsoft Visual Studio / VC98.

I don't know much about building on windows, not sure what else
to provide, so here is the seemingly related source code change:

windows-NT$ cvs diff -rcvs_1_11_9 -rcvs_1_11_10 filesubr.c
