argument. the semantics for ar were changed to zero out the timestamp of each module. nmake relies on the timestamp to tell if the module has changed - added modified 'cc' scripts for linux to add the -P flag. modern gcc's put # lines that confuse nmake - changed make.probe script to drop -nostartfiles for gcc >= 7.0

[+NAME?mamprobe - generate MAM cc probe info]
|
|
[+DESCRIPTION?\bmamprobe\b generates MAM (make abstract machine) \bcc\b(1)
|
|
probe information for use by \bmamake\b(1). \acc-path\a is the
|
|
absolute path of the probed compiler and \ainfo-file\a is where
|
|
the information is placed. \ainfo-file\a is usually
|
|
\b$INSTALLROOT/lib/probe/C/mam/\b\ahash\a, where \ahash\a is a hash
|
|
of \acc-path\a. Any \ainfo-file\a directories are created if needed.
|
|
If \ainfo-file\a is \b-\b then the probe information is written to
|
|
the standard output.]
|
|
[+?\bmamprobe\b and \bmamake\b are used in the bootstrap phase of
|
|
\bpackage\b(1) installation before \bnmake\b(1) is built. The
|
|
probed variable names are the \bnmake\b(1) names with a \bmam_\b
|
|
prefix, \bCC\b converted to \bcc\b, and \b.\b converted to \b_\b.
|
|
Additional variables are:]{
|
|
[+_hosttype_?the \bpackage\b(1) host type]
|
|
[+mam_cc_L?\b-L\b\adir\a supported]
|
|
