Bug #: 52847
Summary: "case" shell quoting problem in top-level makefile
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: sk...@iskunk.org
[Configured on AIX with CC="gcc -mminimal-toc"]
$ gmake bootstrap-lean
echo stage3 > stage_final

The above warning comes from the below line in the top-level makefile, under
the "host and target specific makefile fragments come in here" header:
LDFLAGS = `case $(CC) in *gcc*) echo -Wl,-bbigtoc ;; esac;`
I believe this needs to be written as
LDFLAGS = `case "$(CC)" in *gcc*) echo -Wl,-bbigtoc ;; esac;`
in order to accommodate values of $(CC) which contain spaces.
