What version of Go are you using (go version)?

$ go version
go version go1.15.1 windows/amd64

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

go env Output
$ go env
GOOS=windows
GOARCH=amd64

What did you do?

I try to compile a golang project in which I'm using "github.com/mattn/go-sqlite3" library

What did you expect to see?

A complete compile.

What did you see instead?

These are strange errors to see:

gcc: unrecognized option `-std=gnu99'
cc1.exe: Invalid option `64'
cc1.exe: warning: `-gdwarf-2' not supported by this configuration of GCC
cc1.exe: Invalid option `-Wno-deprecated-declarations'
cc1.exe: Invalid option `-fno-stack-protector'

What is the complete output of go env? For some reason you only listed a couple of lines above.

GCC version egcs-2.91.57 was released in 1998, more than 20 years ago. It would be nice if Go worked with such an old release, but it's not very surprising that it doesn't. You need to update your C compiler.

I'm going to close this issue since we aren't going to go to any extra work to support such an old C compiler. Sorry.
