[Solaris 11.4] binutils/bfd/aout-amiga.c unknown type name PTR for alloca

[nbriggs]

/export/home/briggs/amiga-gcc/projects/binutils/bfd/aout-amiga.c:51:8: error: unknown type name ‘PTR’
   51 | extern PTR alloca PARAMS ((size_t));
      |        ^~~
/export/home/briggs/amiga-gcc/projects/binutils/bfd/aout-amiga.c:51:12: warning: conflicting types for built-in function ‘alloca’; expected ‘void *(long unsigned int)’ [-Wbuiltin-declaration-mismatch]

      |            ^~~~~~
make[4]: *** [Makefile:1761: aout-amiga.lo] Error 1

The actual program text around this is:

#ifndef alloca
extern PTR alloca PARAMS ((size_t));
#endif

It looks as though this probably got broken in

Autoconf 2.60 AC_FUNC_ALLOCA

[isoriano1968]

Same error (on Solaris 11.4.42 CBE x86) also with the 13.1.1 branch using gcc 11.2.0 to build amiga-gcc ..

git clone https://github.com/bebbo/amiga-gcc cd amiga-gcc make update-gcc pushd projects/gcc git fetch origin amiga13.1:amiga13.1 --depth=10 git checkout amiga13.1 popd make clean make min -j$(nproc)

@isoriano1968 - the quick workaround is #include <alloca.h> in projects/binutils/bfd/aout-amiga.c -- if the aim is just to build the compiler etc., one doesn't need the complication of fixing the autoconf scripts and source for the general case.

alloca is not needed at all -> removed that
