I tried compiling the mpir-exp using configure.bat and make.bat. I
modified make.bat to compile and link the fft directory but I get the
following error message when I run 'make check'. I'm looking for
suggestions.

t-bswap.c
mpir.lib(mul_truncate_sqrt2.obj) : error LNK2019: unresolved external
symbol __gmpn_mulmod_2expp1_basecase referenced in
 function __gmpn_mul_truncate_sqrt2
mpir.lib(mulmod_2expp1.obj) : error LNK2001: unresolved external
symbol __gmpn_mulmod_2expp1_basecase
mpir.lib(mulmod_2expp1.obj) : error LNK2001: unresolved external
symbol __gmpn_mulmod_2expp1_basecase
t-bswap.exe : fatal error LNK1120: 1 unresolved externals
ERROR

I also found one error in fft/mulmod_2expp1.c. The function
fft_mulmod_2expp1 is defined as 'void', but the function returned 0.
