66# The following include directive behaves differently, depending on whether
67# the current file has a slash or is a relative filename.  In the first case,
68# make opens the directory of the current file and tries to read from it,
69# resulting in the error message """ line 1: Zero byte read from file".
70# In the second case, the error message is "Could not find ", without quotes
71# or any other indicator for the empty filename at the end of the line.

77# may return a null pointer.  On OpenBSD, this led to a segmentation fault in
78# Buf_InitSize, which assumes that bmake_malloc never returns NULL, just like
79# all other places in the code.
