Too many build failures on newer C++ compilers. Since this
is just testing that the compiler runtime follows the C++
standard it isn't really necessary any more (it was in the
early days of C++ before standardization).
VxWorks 6.x can make environment variables private to each
thread, which doesn't work too well.
A test failure on VxWorks explains how to change the image
configuration to fix this.
Hostnames that begin with one or more digits were not being looked up
by name, causing problems at BNL.
This commit also changes the vxWorks implementation of hostToIPAddr()
to use inet_aton() instead of inet_addr().
Adds new routines for converting numeric strings into the
standard epicsInt8, epicsUInt8, epicsInt16, epicsUInt16,
epicsInt32 and epicsUInt32 types, along with Long, ULong,
Double and Float. These all provide error checking and
detection of extraneous characters. The epicsScanDouble
and epicsScanFloat routines originally in epicsStdlib.h
are replaced by macros that call the epicsParse routine,
and this also provides epicsScanLong and epicsScanULong
to match.
A test file is added to ensure conversions work properly
and report appropriate errors. This file also checks the
native strtod() routine if not used to check whether the
epicsStrtod() code is required on this platform.
* fix libCom exports for things which used to be built differently
* logserver needs winsock
* errlog prefix: fix warnings on win32
* fix dll imports in ioc/db
o changed name, OSD_ATOMIC_INLINE to EPICS_ATOMIC_INLINE
o changed supported data types, unsigned removed and int added (per reveiw at codeathon)
o added add/subtract functions (per reveiw at codeathon)
o now presuming that __sync_synchronize available all gcc 4 mingw does not provide windows mem barrier)
o consolodated on one implemention for Microsoft invarient of cmplr intrinisic or win32 by using macros to config a shared header file
o improved doc in epicsAtomic.h
o added overloaded c++ interface in namespace epics :: atomic to epicsAtomic.h
o added epicsAtomicReadMemoryBarrier and epicsAtomicWriteMemoryBarrier interface to epicsAtomic.h
o changed the implementation so that each of the functions can be individually specified for a particular compiler, os, or in the generic implementation (this is accomplished with macros)
o modified the functional and performance test so that they are based on templates so we can easily support new data types
o modified performance tests to repeat function calls and measure performance using a template
o added CMPLR_SRC_DIRS to ALL_SRC_DIRS, and added compiler/$CMPLR_CLASS) to INSTALL_INCLUDES in CONFIG_COMMON
o added additional compiler specific rule deciding where things are installed to in CONFIG_COMMON
o added compiler specific include install to RULES_BUILD
o changed configure/os/CONFIG.linux-x86.linux-x86 to specify minimum arch is 586 (pentium circa 1995)
o changed configure/os/CONFIG.win32-x86-cygwin.win32-x86-cygwin to specify minimum arch is 586 (pentium circa 1995)
o added epicsAtoimic facility to libCom/Makefile
o added testing and performance measurement to libCom/test/Makefile
