Hello, The attached patch helps fix a build failure of libstdc++ on some variants of VxWorks where the system headers expose an "isblank" macro.
I understand this kind of thing normally is handled through
fixincludes, however fixincludes on VxWorks is very tricky and
we already have
libstdc++-v3/include/c_global/cctype:#undef isblank
libstdc++-v3/include/tr1/cctype:#undef isblank
so the suggestion here is to simply do the same in a couple
more places.
I checked that it gets us through the observed build failure
for VxWorks, then bootstrapped and regtested on native 64bit
linux.
Ok to commit?
Thanks in advance,
With Kind Regards,
Olivier
