I had to reformat Guido's post to read it:

"Same Problem on Solaris 8
Build 32-Bit, gcc 2.95-3

It seems that line 170 in monitor_mm.c is the problem:
if (size > SIZE_T_MAX - MM_MINSIZE + 1)
fatal("mm_malloc: size too big");

size seems to be a different type (uint32)

in defines.h:
#ifndef SIZE_T_MAX
# define SIZE_T_MAX ULONG_MAX
#endif /* SIZE_T_MAX */
#ifndef HAVE_SIZE_T
typedef unsigned int size_t;
# define HAVE_SIZE_T
#endif /* HAVE_SIZE_T */

the line
#define SIZE_T_MAX ULONG_MAX should be changed,
I tried
# define SIZE_T_MAX ((2 << (8 * sizeof(size_t)) - 1)
but got an error (also out of bounds :-(

The definition of SIZE_T_MAX has to be changed to be in the range of the type of
size

From the build log:
gcc -O3 -pipe -mcpu=ultrasparc -m32 -I. -I. -I/usr/local/include
