$ cygcheck gcc
Found: C:/.../cygwin64/bin/gcc.exe
C:/.../cygwin64/bin/gcc.exe
   C:/.../cygwin64/bin/cygwin1.dll
     C:/WINDOWS/system32/KERNEL32.dll
       C:/WINDOWS/system32/ntdll.dll
       C:/WINDOWS/system32/KERNELBASE.dll
   C:/.../cygwin64/bin/cygiconv-2.dll
   C:/.../cygwin64/bin/cygintl-8.dll

so gcc depends on packages libiconv2 and libintl8, and others, providing the 
DLLs, as documented on the gcc-core package summary page:

	https://cygwin.com/packages/summary/gcc-core.html

and building gcc-core etc. will require libiconv-devel and libintl-devel.

Check your package build dependencies, and config logs, as internationalized 
packages, as yours may be, require any or all of gettext-devel, libiconv-devel, 
libintl-devel, po4a to build, and some of your build dependencies may require 
headers or libraries provided by -devel packages, as cygwin itself requires 
libintl8, and those -devel packages to build.

You may want to rerun configure with --verbose messages and look at what the 
failing check script and test program expects to be available to use.
