Description:
------------
Compile Error:
"Zend/zend_bitset.h", line 66: undefined symbol: ZEND_MM_BITSET_LEN

Compiling Environment:
- PHP 7.1.0
- O/S: Solaris 11.3.13.4.0
- Compiler: Developer Studio 12.5 (works fine against gcc 4.8 compiler)

Steps To Recreate:
- Extract source distribution
export CC=cc
export CXX=CC
export CFLAGS="-m64"
export CPPFLAGS="${CFLAGS}"
./configure --sysconfdir=/etc/php --with-config-file-path=/etc/php --with-apxs2=/usr/local/apache2/bin/apxs --disable-all
make

Notes:
- This error doesn't occur with PHP 7.0.13
- This error doesn't occur with GCC 4.8
- The ZEND_MM_BITSET_LEN macro is defined in zend_alloc.c, but is being referenced in zend_bitset.h

If I move the typedef for zend_mm_bitset and the #define for ZEND_MM_BITSET_LEN from zend_alloc.c into zend_bitset.h, it compiles fine.

Note: I also had to make the changes mentioned in bug #70492 in order to get it to compile correctly.

Actual result:
