Does IOC name have any restrictions ?

[Hitesh Dhola via Tech-talk <tech-talk at aps.anl.gov>]

Hello,

I am getting a make error in ioc generation using makeBaseApp, if I use any numeric in name "test".

I created IOC using this,

../bin/windows-x64-mingw/makeBaseApp.pl -t ioc 3test

../bin/windows-x64-mingw/makeBaseApp.pl -i -t ioc 3test

But, make fails with following error.

----------------

3test_registerRecordDeviceDriver.cpp:248:5: error: expected unqualified-id before numeric constant

  248 | int 3test_registerRecordDeviceDriver(DBBASE *pbase)

      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3test_registerRecordDeviceDriver.cpp: In function 'void rrddCallFunc(const iocshArgBuf*)':

3test_registerRecordDeviceDriver.cpp:291:19: error: unable to find numeric literal operator 'operator""test_registerRecordDeviceDriver'

  291 |     iocshSetError(3test_registerRecordDeviceDriver(*iocshPpdbbase));

-------------------------

It works fine if i use non-numeric, say using 'rtest' instead of '3test' is working fine. I am working on Windows 10 and MSYS environment.

Do we have any restriction in naming convention for IOC? or this is something else ?
