Subject: Remove unused sparc_sunos4_mach_dep.s file
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=974e07b74460e86489ec8e75d50366e962cd87ec;p=gc

Remove unused sparc_sunos4_mach_dep.s file

Issue #269 (bdwgc).

It had been used only by OpenBSD/sparc in Makefile.direct previously.

* Makefile.am (EXTRA_libgc_la_SOURCES): Remove sparc_sunos4_mach_dep.s.
* Makefile.direct (SRCS): Likewise.
* sparc_sunos4_mach_dep.s: Remove file.
