[Bug binutils/5146] New: bfd build fails in alloca-conf.h when built without gcc

[haubi at gentoo dot org]

When building binutils-2.18 with native cc on hppa-hpux11.11,
include/alloca-conf.h fails to correctly include <alloca.h>, or to define 'PTR'
when included in bfd/som.c:

libtool: compile:  cc -Wp,-H256000 -DHAVE_CONFIG_H -I.
-I/source/binutils-2.18/bfd -I. -DHOST_HPPAHPUX -D_LARGEFILE64_SOURCE
-DHPUX_CORE -I. -I/source/binutils-2.18/bfd
-I/source/binutils-2.18/bfd/../include -O3 -c /source/binutils-2.18/bfd/som.c -o
som.o
cc: "/source/binutils-2.18/bfd/../include/alloca-conf.h", line 15: error 1000:
Unexpected symbol: "alloca".
cc: panic 2017: Cannot recover from earlier errors, terminating.
gmake[4]: *** [som.lo] Error 1
gmake[4]: Leaving directory `/build/binutils-2.18/bfd'
gmake[3]: *** [all-recursive] Error 1

gmake[1]: Leaving directory `/build/binutils-2.18'

This line 15 is
  extern PTR alloca (size_t);

The problem causing cc to fail is that 'PTR' is not typedef'd or defined before
- don't know where this should be done.

Instead, <alloca.h> could be used here, but bfd/configure.in does not check for
"alloca.h":
