1263* This function allocates a free C Runtime file handle and associates

1265* temperary fix for WIN95's brain damage GetFileType() error on socket
1266* we just bypass that call for socket
1267*
1268*Entry:
1269* long osfhandle - Win32 HANDLE to associate with C Runtime file handle.
1270* int flags - flags to associate with C Runtime file handle.
1271*
1272*Exit:
1273* returns index of entry in fh, if successful
1274* return -1, if no free entry is found
1275*
