Hello, To convey the value of libsubdir to sub-makes, gcc/Makefile.in has
# Flags to pass to recursive makes.
# CC is set by configure.
# ??? The choices here will need some experimenting with.
export AR_FOR_TARGET
...
export libsubdir
then:
FLAGS_TO_PASS = \
...
(libsubdir not here)
This is not working well on cygwin environments where environment
variable names are translated to uppercase (so sub-makes evaluating
the variable with the lowercase name don't get the value).
The attached patch is a suggestion to address this by simply adding
"libsubdir" to the list of explicit FLAGS_TO_PASS.
Used in-house for a while, with gcc-6 on a wide variety of host/target
configurations.
Bootstrapped and regression tested with mainline on x86_64-linux.
OK to commit ?
Thanks in advance,
With Kind Regards,
Olivier
