I built a simple hello world application in lcc-win32:

#include <stdio.h

int main(void);

int main(void) {
printf("hello world\n");

return 0;
}

Originally, lcc-win32 builds an exe of 100kb! I found out how to get
the exe size down to 31kb by unchecking the Compiler > Generate debug
info under Project Configuration, but 31kb is almost twice the size of
the exact same code under WinGW, which builds an exe of only 16kb.

Is this a result of a completely different stdio.h file?
Are there any other optimizations or settings that I can do under lcc-
win32 to get the filesize down to a more respectable size?

I don't know about switches for lcc.exe. If you link separately with
lcclnk.exe you can use:

lcclnk -dynamic -S -o hello.exe hello.obj

for example, to reduce the size. Your example reduced to about 3600 bytes..

That does reduce the filesize significantly, but the application will
fail on installations where the lcclib.dll is not present. Not quite
the solution I was looking for as I would like the application to be
self contained.
