Linker script which gives the linker some special instructions.

Not sure offhand (my version of GCC doesn't include it) but probably
contains instructions to the linker about DXE files.

Contains the startup code used when profiling.

Some routines used by the DJGPP debuggers.

Software math emulation; you can link this with your program and it will
be able to run on machines without FPUs.

> C:\DJGPP\lib\libg.a

A library with nothing in it, which prevents programs which try to link
it (it's traditionally a debugging library) from failing.

> C:\DJGPP\lib\libgpp.a

C++ classes written by GNU.  Now deprecated.

> C:\DJGPP\lib\libm.a

Math functions.  libc contains some, but these handle errors more
gracefully, are sometimes more accurate, and include some more advanced
functions.

> C:\DJGPP\lib\libpc.a

Another empty library for compatibility.

> C:\DJGPP\lib\crt0.o

The startup code linked with programs when not profiling.
