Unfortunately I can't build cygwin anymore:
cygheap.cc: In function `void * crealloc(void *, long unsigned int)':
cygheap.cc:295: `brk' undeclared (first use this function)
cygheap.cc:295: (Each undeclared identifier is reported only once
cygheap.cc:295: for each function it appears in.)
cygheap.cc:295: `brkbase' undeclared (first use this function)
cygheap.cc:295: `brktop' undeclared (first use this function)
Where are all these symbols used in that `inheap()' macro?
