I've made small adjustments over the years to keep Lcc-Win32 (32-bit) running on my PC.
Here are my "tweaks" to the Lcc-Win32 INCLUDE and LIB folders.

INSTRUCTIONS:
1) Install Lcc-Win32 (32-bit) as you normally would.
2) Overwrite the \LIB\ and \INCLUDE\ folders with my tweaked versions.
These work for me, they should work for you too.
