Subject: Missing volatile in declaration of GC_with_callee_saves_pushed
X-Git-Tag: gc7_6_0~22
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=65b50c089d3189ad3f085c9f5dda998277888117;p=gc

Missing volatile in declaration of GC_with_callee_saves_pushed
(fix for commit 8ffc3db)

Otherwise MS VC reports a warning at level 4.

* include/private/gc_priv.h (GC_with_callee_saves_pushed): Add
volatile for arg (to match the function definition).
