Subject: [ng] am: implement $(am__tolower) and $(am__toupper)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cf8fc13a4f3ff8d03cdb93019e5d5c2796937dca;p=thirdparty%2Fautomake.git

[ng] am: implement $(am__tolower) and $(am__toupper)

These new make functions will be useful in future changes.

* lib/am/header-vars.am (am__toupper, am__tolower): New make functions.
* t/internals.tap: Test them.
