Subject: [PATCH svn-fe] fast-import: make code "-Wpointer-arith" clean
Date: Mon, 28 Feb 2011 15:32:10 -0600 [thread overview]
Message-ID: <20110228213210.GD1942@elie> (raw)
In-Reply-To: <7vhbbolm5q.fsf@alter.siamese.dyndns.org>
The dereference() function to peel a tree-ish and find the underlying
tree expects arithmetic to (void *) to work on byte addresses. We
should be reading the text of objects through a char * anyway.

This should fix it, I suppose? A
-std=c99 -O3 -Wall -W
-Wno-sign-compare
-Wno-unused-parameter
-Wno-missing-field-initializers
-Wno-empty-body
-Wno-pointer-to-int-cast
-Wno-type-limits
-Wno-unused-but-set-variable
-Wold-style-definition -Wpointer-arith -Wvla
-Wdeclaration-after-statement -Werror
build passes, except for an "unsigned long expire" in builtin-reflog
that confuses this copy of gcc.
