Subject: Use -MM option to gcc in makegen-cc to generate header file lists,
X-Git-Tag: 20090517-FFI~1145
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=f81f0d1afce8921a4cd4fc380eda35a837ae9c4d;p=mit-scheme.git

Use -MM option to gcc in makegen-cc to generate header file lists,
not -M; -MM inhibits inclusion of system files, which not only are
superfluous but also, if absent, cause errors to be silently inserted
into the resultant Makefiles, which make then chokes on.
