Did you strip debug symbols? Did you turn on the optimizer? By default,
debug symbols are left in the .exe so if it crashes you can debug it. To
make as small an exe as possible:

for compiling sources:

gcc -c -O3 -mpentium -ffast-math -fomit-frame-pointer whatever.c

(outputs whatever.o object file)

and linking objects:

gcc whatever1.o whatever2.o -o whatever.exe -s -lalleg

Note that you won't be able to debug your program with these options, so
only use them on sources that you have working properly. Programs that use
allegro are typically around 200k at least. You can make them even smaller
by using an executable packer like DJP or UPX. See the DJGPP FAQ for more
information about making smaller .exes.
