re: request for feature: umask control with GNU make

[Brian Vandenberg]

This is in response to an older thread from quite a few years back:
http://groups.google.com/group/gnu.utils.bug/browse_thread/thread/277afe41cc5c0d67/22cc0a52143931ea?lnk=st&q=makefile+umask&rnum=1&hl=en&pli=1

The original problem and suggested solution were: how to control umask
globally from the makefile (assuming make never implemented a native
feature for it), and the suggested solution was:

SHELL = umask 002; exec /bin/sh

This approach only works on some platforms.  In Solaris, for example,
it causes segfaults.

A more robust solution (using bash; I'm sure there's an 'sh'
equivalent):

SHELL = /bin/bash --noprofile -c 'umask 002; shift; eval "$$2"' --
