build failed with gcc trunk on cygwin host

["M R Swami Reddy" <MR.Swami.Reddy@xxxxxxx>]

Hello,

I am trying to build the gcc tools on cygwin host. But the build failed with 
below errors:
====
$ gcc  -I../../../trunk/libdecnumber -I.  -g -O2 -W -Wall -Wwrite-strings -Wstr
ict-prototypes -Wmissing-prototypes -Wold-style-definition -Wmissing-format-att
ribute -Wcast-qual -pedantic -Wno-long-long  -I../../../trunk/libdecnumber -I.
 -c ../../../trunk/libdecnumber/dpd/decimal128.c
 In file included from ../../../trunk/libdecnumber/decNumber.h:42,

                  ../../../trunk/libdecnumber/decContext.h:59:61: gstdint.h: No 
such file or directory

$ gcc -v
Thread model: posix
gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

Could you please advise the reason for build for the above build fail. Thank you.

Thanks
Swami
