I copied unix.exp to unix-sysroot.exp and added this to it:
if {[info exists env(DEJAGNU_UNIX_SYSROOT_FLAGS)]} {
set_board_info ldflags "$env(DEJAGNU_UNIX_SYSROOT_FLAGS)"
}
I figured I would deal with LOCPATH and GCONV_PATH later. When
I do a partial testrun, I don't get any failures but I do get some
new unresolved tests like this:
Download of ./20000108-1.exe to unix-sysroot failed.
UNRESOLVED: gcc.dg/20000108-1.c execution test
Have ever seen this error?
