Hi All,

 The following compiling error welcomed me when I compiled EPICS

3.15.4 on Debian 9.

```

 /usr/bin/g++ -D_GNU_SOURCE -D_DEFAULT_SOURCE -D_X86_64_

-DUNIX -Dlinux -O3 -g -Wall -mtune=generic -m64 -I.

-I../O.Common -I. -I. -I..

-I/epics/bases/base-3.15.4/include/compiler/gcc

-I/epics/bases/base-3.15.4/include/os/Linux

-I/epics/bases/base-3.15.4/include -c ../epicsExceptionTest.cpp

../epicsExceptionTest.cpp: In function ‘void epicsExceptionTestPrivate()’:
../epicsExceptionTest.cpp:61:49: error: size of array is too large
         char * p = new char [unsuccessfulNewSize];
                                                 ^
../epicsExceptionTest.cpp:74:38: error: size of array is too large
             char [unsuccessfulNewSize];
                                      ^

```

 I saw the same compile error in old tech-talk [1], and one of the

following solution allowed me to compile the EPICS base properly.

1) edit static size_t unsuccessfulNewSize = numeric_limits < size_t > ::

max (); in epicsExceptionTest.cpp

2) USR_CXXFLAGS = -std=gnu++98 in configure/CONFIG_COMMON

  gcc info is

```
gcc --version
gcc (Debian 6.3.0-18) 6.3.0 20170516

gcc -dM -E - </dev/null |grep STDC
#define __STDC_HOSTED__ 1
#define __STDC_UTF_16__ 1
#define __STDC_IEC_559__ 1
#define __STDC_ISO_10646__ 201605L
#define __STDC_NO_THREADS__ 1
#define _STDC_PREDEF_H 1
#define __STDC_IEC_559_COMPLEX__ 1
#define __STDC_VERSION__ 201112L
#define __GNUC_STDC_INLINE__ 1
#define __STDC_UTF_32__ 1
#define __STDC__ 1
```

  Best,
  Han
