+Subject: [PATCH 004/135] Revert "Move asm machine-dependent files to 'src'
+ folder" (partly)
+
+Asm files moved back to base folder to avoid build issues (reported
+for NetBSD and Solaris on Sparc).  Alternative way is to adjust
+configure.ac and Makefile.am properly but it requires more efforts
+(including testing).
+
+* Makefile.am (EXTRA_libgc_la_SOURCES): Remove "src/" prefix.
+* Makefile.direct (SRCS, mach_dep.o): Likewise.
+* src/ia64_save_regs_in_stack.s: Move to base folder.
+* src/sparc_mach_dep.S: Likewise.
+* src/sparc_netbsd_mach_dep.s: Likewise.
+* src/sparc_sunos4_mach_dep.s: Likewise.
