yeah, could be.

still using 2013 here ATM for Win32 development. good enough for now.


dunno about Texas Instruments' compiler.

looking it up, apparently it defaults to C89 mode, but a C99 subset can 
be supported via compiler options.

apparently absent features (depends on target, for the chips I am using):
wide character support;
complex numbers;
floating point support (only supported on targets with an FPU);
various printf format specifiers;
...

apparently, the C++ compiler for the target also does an 'Embedded C++' 
variant.

though, on this target (MSP430G2xxx), the limited ROM space is a much 
bigger issue than the lack of some features. everything still needs to 
fit in a few kB of ROM (programs are fairly small and one-off, features 
added and removed with an eye to the remaining RAM and ROM space).


once long ago (~ 15-17 years ago), I messed some with compiling code for 
M68K, Z80, and 6502 in emulators. the compilers I was using at the time 
only did K&R.

not sure if many people are still seriously using Turbo C and DOS and/or 
Win16. I have encountered some embedded terminals and other things 
apparently still based on a shell over Windows 3.x, so it probably is 
still in use in some places.

I guess it is whatever is cheap and easy...


like, the chips I am using were mostly because they are reasonably 
affordable and DIP based (bulk price is around $0.50 each). DIP is 
useful for small-scale as it allows using sockets and wire-wrap (having 
PCBs made isn't free either).

one can get a lot more but it costs more...
