Subject: Re:  New: bfd build fails in alloca-conf.h when
 built without gcc

Hi Michael,

Hmm, the problem here, it seems to me, is the alloca-conf.h header using PTR 
when it is not defined.  (It is defined in include/ansidecl.h, but 
alloca-conf.h does not include that header).

Fixing the bfd configure script so that the system alloca.h is used instead 
does not seem to me to be sufficient - the problem can still arise in other 
build directories.  So please could you try out the patch below (which fixes 
the header itself) and let me know if it works for you ?

Cheers
   Nick
