php4apache.dll won't build - _highlight_file

Hi all, I've been getting a link error for a week or so when trying to build php4apache.dll whereas it used to work before. I've got no idea what's going on. Could someone please tell me how to fix this? The build reports end with: --------------------Configuration: php4apache - Win32 Release_TS_inline-------------------- Compiling... mod_php4.c D:\compile\apache\1.3\apache-1.3_20001026161200\src\include\../os/win32/os.h(112) : warning C4142: benign redefinition of type D:\compile\php\php4-200010261045\sapi\apache\mod_php4.c(136) : warning C4018: '!=' : signed/unsigned mismatch D:\compile\php\php4-200010261045\sapi\apache\mod_php4.c(583) : warning C4101: 'tmp' : unreferenced local variable php_apache.c D:\compile\apache\1.3\apache-1.3_20001026161200\src\include\../os/win32/os.h(112) : warning C4142: benign redefinition of type sapi_apache.c D:\compile\apache\1.3\apache-1.3_20001026161200\src\include\../os/win32/os.h(112) : warning C4142: benign redefinition of type Linking...
